As you will see in this updated Koofr review, we’ve taken this cloud-storage- service-slash-multi-cloud-manager hybrid for another spin to see how it fares now. While it’s still one of the best cloud storages you can use, it’s also a very simple one. Depending on your needs and expectations, this can be a good or a bad thing.

Key Takeaways:

  • Koofr is a cloud storage service that also enables you to connect your Dropbox, Google Drive and OneDrive accounts to it.
  • It’s simple to use and with great collaboration and sharing options, and it also features Office 365 integration so you can create Microsoft Office documents in it.
  • Koofr has a free plan with 10GB of storage space and seven paid plans that go all the way to 10TB of storage.
  • Its lack of zero-knowledge encryption, limited features and high price prohibit it from being the best cloud storage option you can use. 

Even though Koofr cannot compare to the absolute crème de la crème of the cloud storage market — and pCloud — it’s still an interesting storage service that excels in several categories and has a couple of very interesting features. Read on to learn if it is worth your time and money.

    Cloudwards retested all the features, added new screenshots and completed new speed tests.

  • 03/30/2022

    Updated the review to reflect that Koofr expanded its free plan from 2GB to 10GB.

  • Koofr is a cloud storage service that specializes in file sharing and providing access to all your online files in one place. It does this by enabling you to connect to several popular cloud storage services whose files you can manage from Koofr itself.

  • With files that are encrypted during transit and at rest, two-step verification and the option to password protect your shared files, Koofr is a very secure cloud storage service. The only significant security feature it lacks is zero-knowledge encryption. If this is a deal-breaker for you, we have a list of best zero-knowledge cloud services.

  • As you can see in our OneDrive review, both it and Koofr have their distinct pros and cons. If you rely on Office 365, then OneDrive is the superior choice. However, if you are searching for a cloud storage solution that can also connect to multiple cloud storage providers (including OneDrive), Koofr is what you are looking for.

Strengths & Weaknesses


  • Easy to use
  • Secure & GDPR-compliant
  • Web, desktop & mobile apps
  • Integrates with Google Drive, OneDrive & Dropbox
  • Good sharing capabilities & Microsoft Office 365 integration


  • No block-level sync
  • No zero-knowledge encryption
  • Limited support options


80 % – Good

When it comes to features, Koofr won’t wow you with its modest list — at least when it comes to cloud storage. On the other hand, it has two standout features in the form of Office 365 integration and cloud management capability — though, as we’ll see later in this article, Koofr shouldn’t be mistaken for a viable MultCloud alternative.

The biggest advantages Koofr has are its strong security and privacy, simple design and good transfer speeds. While it’s not as good as some more advanced products on the cloud storage market — such as the — if you want a cloud storage that can also be used to keep all your files in one place, Koofr might be exactly what you are looking for.

On the desktop app, Koofr can create a virtual network drive using the WebDAV protocol. By enabling this feature, you will be able to access Koofr files directly from your computer, without them taking up any space on your hard drive. Unfortunately, if you are a Windows user, the maximum file size you can download or upload this way is a mere 50MB.

Manage Multiple Cloud Services

You can connect certain cloud storage services to Koofr. However, this consists of just three cloud storage providers: Dropbox, Google Drive and OneDrive. Even though Koofr was one of the honorable mentions in our best cloud-to-cloud management services list, we have to make it absolutely clear that it isn’t a true multi-cloud manager.

So, while you can add these cloud storage services to it and perform some basic operations — such as moving files from one cloud storage to another — you won’t be able to sync files between them or use Koofr to automate your data transfers.

It’s best to think of Koofr as a cloud storage service first and foremost, albeit one that lets you access your remote files on several other cloud services as well. If you don’t expect anything more than that, you will find that it can be very handy to have all your online files available in one place for download, renaming and other such rudimentary actions.

Productivity Features

Since Koofr has integrated with Microsoft Office 365, you will be able to create Office documents in it, but this is only available in the web app. When you click on the green “add” icon, a dropdown menu will inform you that, besides the option to upload files and folders, and create folders, you can also create Microsoft Word, Excel, Powerpoint and Notepad documents.

koofr office
Koofr’s Microsoft Office 365 integration lets you create Office documents inside its web app.

Unless you are on a paid plan, you won’t be able to edit these documents once you have created them, so this feature really isn’t useful for free users. Koofr has limited file versioning — it saves only the last five iterations of your files, and lets you recover deleted files up to 30 after you’ve deleted them. These deleted files do not count toward your total cloud storage space.

The built-in messaging option is very convenient, since it will allow you to better communicate with your collaborators. Koofr even has a browser extension; you can find it here. It functions similarly to the one from Evernote, letting you save images from almost anywhere on the web directly to your Koofr storage.

Free Plan


62 % – Fair

Apart from its free account version (called the Starter plan), Koofr has seven paid plans. It’s important to note that the prices on Koofr’s website are in euros; we’ve converted these into U.S. dollars, but the exchange rate is subject to fluctuation.

All plans, regardless of whether they are free or paid, can connect to the same cloud storage services. There’s no limit to upload or download file size, and all have unlimited sharing.

  • : 10GB
  • : 100GB
  • : 250GB
  • : 1TB
  • : 3TB
  • : 10TB
  • : 20TB

Koofr’s paid plans are named like clothing sizes, so we start at S, which gives you 10GB for around half a buck, and go all the way up to 10TB for $70 on the 10XL plan. Overall, while its M and L plans are cheap enough if you need a bit more storage, it quickly starts to lose value the further you go. For example, Koofr’s XXXL plan (2.5TB) costs around $23, while Icedrive gets you double that at 5TB for $17.99.

koofr pricing
Koofr has a free plan and seven paid plans.

When compared with unlimited storage providers, Koofr’s pricing becomes even more unfavorable. has unlimited storage for $20 a month ($15 per month if billed yearly) and OpenDrive is just $9.95 per month.

Koofr Free Plan: Starter

Koofr’s free option, referred to as the Starter plan, with it you get a Koofr cloud storage lifetime subscription of 10GB storage space. This is is about average for cloud storage services, but Koofr still didn’t make our list of best free cloud storages.

However, if you are planning to use it as a free collaboration tool with your Dropbox, Google Drive and OneDrive accounts connected to it for easier sharing, then you can do much worse.

Ease of Use

88 % – Very Good

Koofr is primarily controlled via its web app interface, though it also has a desktop app and mobile apps. The web interface — where you’ll find the majority of its functionality– is clean and simple looking. On the left side, you will see your connected cloud services, shared and deleted files, while the center of the UI is devoted to managing those online files.

Another important feature that greatly contributes to Koofr’s ease of use is its fast and precise search tool. When you search for files, the results are near-instantaneous, and the search results also include where the files are located. This is very handy, especially if you have several connected cloud storages of the same type.

Koofr supports image and PDF files and previews, as well as playback for audio and video files. Its file manager allows for the usual options, so you will be able to copy, download and delete your remote files, but you can also move them from one connected cloud storage to another. The mobile app — available for both Android and iOS devices — is also very solid and works similarly to the web app.

Koofr has mobile apps for Android and iOS devices.

Koofr Desktop App

After you have installed the Koofr desktop app, it will create a separate sync folder on your computer. When you upload files to it, they will then be synced to your web app as well. You will be able to manage these files in the “my desktop sync” folder on the web app. Besides this, the desktop app isn’t particularly feature rich.

Koofr’s desktop app has a sync folder and all the files you upload here will be synced to the web and mobile app.

Apart from uploading and opening files, the desktop app won’t allow you to share these files or move them from one location to another. It also doesn’t give you the option to access your connected cloud accounts. While it’s nice to have a desktop sync folder, Koofr’s desktop app isn’t particularly useful or developed.

File Sync & Sharing

72 % – Decent

As we already mentioned, file sharing in Koofr is very easy and intuitive. Simply click on the “share” button and you will see the available sharing options. You can create upload links or share your remote files via email. There’s also the option to invite collaborators and set their permission levels.

koofr share
Koofr has several sharing options, and it also allows you to invite collaborators and set their permission levels.

However, you can only set a password when you are sharing your files, and not when you add people. This would have been an excellent security addition, regardless of the permission levels you’ve granted to your collaborators.

When you select the “send link” sharing option, you will be able to somewhat customize how this will be done. First off, you can set up a password to protect this file. The password is a randomly generated six-digit code, and you cannot set it yourself.

Second, you can set the file expiration date. You can also share files on your local hard drive, though this option is reserved for paid accounts.

Koofr File Sync

Koofr’s file sync comes in the form of its desktop app. Once the installation is complete, Koofr will create a “Koofr folder” on your desktop. All the files you copy — or drag and drop — here will sync to the web app, too. Though, as we’ve mentioned in the ease-of-use section, the desktop app isn’t particularly good and Dropbox easily beats it when it comes to file sync options.

The good news is that file sync across the web, desktop and mobile apps is very fast. Given that Koofr doesn’t have block-level sync, this somewhat makes up for it. Selective sync — the option to choose which files and folders you would like to sync — is also not present.


82 % – Good

We conducted our 1GB speed test from Serbia, using an internet connection with a 100 Mbps download speed and 20 Mbps upload speed. This is relatively close to Germany, where Koofr’s servers are, but if you are farther away, both uploading and downloading can take longer.

Uploading this file took about nine minutes, but it should have taken just seven minutes. The download was markedly slower — it usually takes around 90 seconds at that connection speed, but in our case it took almost three and a half minutes on the first try and nearly three minutes on the second.

First Attempt:Second Attempt:Average:
Upload 8:30 minutes9:30 minutes9 minutes
Download3:20 minutes 2:50 minutes 3 minutes

While this isn’t ideal, it is by no means slow. For example, OpenDrive took an hour to upload the same file size. A bigger problem is that Koofr doesn’t have block-level sync. Without this, any time you make a change to a file, the entire thing will need to be reuploaded, which results in longer sync times.


85 % – Very Good

Security is another area in which Koofr does very well. When files are in transit between your computer and any Koofr app, they are encrypted using an SSL/TLS encryption protocol. While at rest on the server, the files are protected with “server-side encryption,” which Koofr customer support clarified as AES 256-bit encryption, which is excellent. 

However, you can also add an encryption service to Koofr, which also provides AES 256-bit encryption, ensuring a high degree of protection from cyberattacks like ransomware.

Koofr also has two-factor authentication. Turning this on guarantees that no one will be able to take over your account without also having access to your email. To turn it on, you will need to download a time-based password authentication app such as Authy or Google Authenticator, depending on which platform you are using.

81 % – Good

Koofr’s privacy ticks off many of the boxes we like to see in the services we review. To begin with, as a European company, it is fully GDPR-compliant. This means a lot when it comes to the privacy of your data and personal information. Its servers are hosted on ISO 27001 certified data centers which are located in Germany.

Koofr does not use any tracking tools on its website and the only required cookies are the ones that keep you logged in to the web app. The file metadata information — such as the file size, name, type, etc. — is stored on different servers than the ones where your actual file contents are.

Koofr guarantees that it won’t send you unsolicited marketing emails or sell your information to any third parties. That being said, its terms of service does point out that you are responsible for the content you upload. If required, Koofr will comply with legal requests and they also adhere to international copyright laws.

The biggest privacy (and security) disadvantage is that Koofr doesn’t have zero-knowledge encryption. Not every cloud storage has this feature, but those that do have zero knowledge are far more secure and private. Our recommendation is that you set up a strong password and use encryption software to make sure your Koofr account is fully protected. 

Customer Support

When it comes to customer support, Koofr only has one support channel — email. There is no phone or live chat support. To contact Koofr support, you either need to go through the website or be logged in to the web app and click on the “help and support” link. This latter option will take you to Koofr’s support center where you can browse through its help section — consisting of a couple dozen frequently asked questions.

If you do not find an answer to your issue here (and the odds that you won’t are good, since the knowledgebase is very limited in scope), you will need to write to Koofr support. There are three options here: one for account-related questions, one for bug reporting and a third to permanently delete your entire account.

Koofr’s customer support is limited to email.

We tried sending a quick question to see how long it would take for support to get back to us. To our delight, it only took a couple of minutes. We love seeing professional commitment like this, since some services, such as Otixo, can take more than a week to reply. A fast response rate does a lot to mitigate a lack of other support channels, like live chat and phone support.

The Verdict

Taken as a whole, Koofr can best be described as a lightweight cloud storage service suitable for sharing small files. What sets it apart from similar storage apps are its Office 365 integration and basic multi-cloud management features. While having all of these in one app is practical, you are still better off using MultCloud or cloudHQ for complete cloud-to-cloud management.

Bottom line: if the thought of having a single cloud storage that also provides unified access to all your remote files for Google Drive, OneDrive and Dropbox sounds enticing, then Koofr might be right up your alley. However, if that isn’t the case, Koofr doesn’t really have any stand-out features that would make us recommend it over Sync, pCloud or Icedrive.

We hope that you have found our Koofr review to be an informative and enjoyable read. Are you a Koofr user? Are you happy with the service? Do you think that we’ve been too hard on the service, or that there were some features we neglected to mention? Tell us in the comments below. As always, thank you for reading.

16 thoughts on “Koofr”

  1. I’ve been trying Koofr for 3 weeks and I’m liking the service particularly it supports both a sync folder and a network drive plus I like how it supports mounting other cloud services like Amazon Drive.

    Also I’ve been exchanging emails with the support team all the time with same day reply, so your verdict that Koofr doesn’t have email support is incorrect.

  2. Koofr is very good, fast upload, sync, can play video mp4 all common audios, .doc prewiew ….

  3. I love this service. Very full featured. Sync folders. Capable native clients. Awesome upload and download speeds. Above all, excellent customer service. I am extremely satisfied with this cloud storage service.

  4. I started using this service a few days ago. So far liking it very well. Very fast upload and DL sync speeds. Also very important that my data is stored on servers in EU and not in US. By inviting friends you can extend the free plan to 10gb. Also free plan is free for life.

  5. From my experience Koofr has pretty decent speeds. And it has some pretty good deals as well, not from their official website but from Stacksocial or other affiliated online stores like ‘windowscentral digital offers’ for example. They are basically selling the same products. I bet many Cloud service users have heard of these websites. They sell tons of tech online services and hardwares.

    Currently Koofr has three offers on their websites. 30usd for 100GB, 60usd for 250GB and 170usd for 1TB. All of them are lifetime subscriptions. If you make purchase from Stacksocial, you can use chrome extensions to find decent coupon codes. I got 1TB subscription and it shows ‘Plan XXL, 1TB, Valid till the end of time’ just in case someone is interested. and of course you cannot activate multiple codes in one account. Only the one with largest capacity counts.

    BTW Koofr is continuously adding new features in their website. Their UI is super clean, making it intuitive for users. Based on their Changelog, developers added ‘New and improved text editor’ 3 days ago and ‘Customize the passwords for Send and Receive links’ 20 days ago. Personally I feel like developers from Koofr are taking it seriously. I use it as a optional storage service. My primary usage of it is to transfer files from one cloud to another by connecting it with my Google Drive, Onedrive and Dropbox. I just hope they can integrate other clouds by WebDAV so I can connect it with my lifetime 2TB pCloud too.

    For those who’re not willing to pay that much to subscriptions I think it’s worth a shot.

  6. Koofr seem genuinely committed to customer privacy and open standards. Their site does not count any trackers in adblock/privacy software i have found. They allow and encourage (through blog posts) the use of WebDav and Rclone/crypt, making their service cross platform/architecture. Their blog also provides detailed guides for using backup software and NAS drives with their service. My few dealings with support have been very positive, with friendly and knowledgeable communication. While their apps aren’t as feature rich as some of the large providers- I do feel a lot safer leaving my data with them over many of their competitors. My biggest disappointment is the highest lifetime sub available is 1tb!

    1. We are aware of this. However, we have to count it as a negative, as any service could claim the same. Having to use a separate piece of software, while other services offer zero-knowledge out of the box is just objectively worse.

  7. You should update your review as Office Online is now included in Paid account.

    1. Thank you very much for this information! We will update the review accordingly soon.

  8. Love it! I spent a few weeks comparing Koofr with other cloud storage with lifetime subscriptions such as IceDrive & Pcloud. Although Icedrive and Pcloud are more secure, Koofr lifetime subscription is much cheaper. And after studying Koofr I figured it’s secure enough for me to store my data. AES256 encryption for your data at rest & TLS encryption while your data is in transit (same as banking online). Koofr also doesn’t track you. Ran tests including making them delete my account & data. They did. These guys are very transparent and are always looking to improve. With their servers being located in privacy friendly Germany unlike Pcloud’s US location.

  9. Koofr the upload speed is very slow 1.7 mb / s it takes a long time to send the files I am not satisfied

  10. Recently signed-up for a Koofr paid plan and carried out a cursory review. So far I have to say I like it very much.

    + Great online Office integration. For me online doc editing is important especially for spreadsheets. This means its also easy to use on my Chromebook.
    + Lighting-fast upload/download speeds!
    + Good security.
    + Excellent Linux client app, does what it says on the tin.
    + Android app excellent.
    + Generous amount of storage for a reasonable price.

    – Shame no zero-knowledge. Need a vault as with pCloud. This security restriction means I can only store non-confidential files in Koofr. For the price, I shouldn’t have to use a another tool like Cryptomator to achieve zero-knowledge, when other cloud systems include this.
    – Connects to multiple cloud services, but alas, files cannot be edited online, only Koofr docs.
    – Lack of file-level bookmark/favourite, for me this is a useful feature that’s missing.

  11. I’ve been with since they started doing business. Their lack of support for U2F security keys, their email-only support (often days after a problem’s reported), and their slow speeds finally prompted me to look for another subscription service. I dismissed pCloud as an option after reading the company confessing to snooping paying customers’ files (hashes…). Worse, they demand more money for what should be part of the plan–zero-knowledge encryption. There are already other successful, fast sync options out there that don’t offer zero-knowledge encryption.

    Enter Koofr. I got a deal on a non-refundable lifetime subscription and have been trying to get the system to work for months now. The first big problem for me is the way they manage syncing. If you’re not careful with how you set up sync, you can ruin your synced folders’ contents. I’m not a tech-head. I want tech that works simply out of the box. Creating sync folders from my computer to Koofr wasn’t immediately intuitive.

    Next problem I have with Koofr is really MY fault. I thought that today with all the news of weekly security breaches or governments trying to pass invasive anti-privacy legislation, any data storage company would offer as a fundamental part of their service zero-knowledge architecture. So I stupidly didn’t read up enough on Koofr to realize this is NOT the case with them. I have to encrypt files before uploading–but this means I can’t see the names of files when I need to choose one out of hundreds to download or update.

    This brings me to another big problem I have with Koofr. It does NOT offer block level syncing. I had to update a single 2GB file earlier tonight. 4-hours later, Koofr IS STILL SYNCING EVERY SINGLE FILE! When I look in the process field, I see it’s updating HUNDREDS OF GBs OF FILES. Uber-wasteful!

    Two positives: upload speeds are much better than’s and I can play music directly in Koofr–don’t have to download. This latter is great for accessing tunes when away from home.

    I’ll keep using Koofr for music files and pre-upload-encrypted folders I almost never have to access. I could deal with the way Koofr sets up sync folders. But not having block level syncs and not offering desperately needed today zero-knowledge encryption have forced me to pay for other subscriptions. I agree with commenters above who point out that for the price we shouldn’t have to use other software to encrypt our files before storing them with Koofr.

  12. I have been using PCloud for more than 5 years and it’s been very reliable. I got the 500 GB that time when it was around $ 125. Due to the increases in oil prices recently, they have now increased the price to $175. I hope they don’t add gas to it so that it doesn’t become expensive.

    Anyway, I recently bought Koofr for $29 for 100 +10 GB through a promotion on GDGT deals.

    I was able to compare the two and I found out that pCloud is better.

    First, pCloud’s default folder is a network drive. That means, if you don’t know where the drive installs, your C drive will not be consumed. This is not true for Koofr. The default drive is in C, which you cannot move to other drives like D. In order to avoid filling up your C drive, you have to delete the default folder and ignore it. You can either use the Webdav or set a syncing folder in a different drive. They also offer local drive, which I believe is not necessary since you can already do that with sync option.

    Second, pCloud has a public folder that can host static websites. There is no such option for any other cloud providers in this list. When you share a link, the recipient can easily download the file. It doesn’t take you to its website, where you need to click download, like we transfer or mega.

    If you want to test your website, you can use pCloud’s public folder to see the finished product. All you need to do is to get the link address for the index.html file. You can create hundreds or thousands of websites. The link is quite long so you need a link shortener such as bitly.

    pCloud is the greatest option if you are a web developer. One other website that offers static website hosting is Amazon S3. But you need to create a bucket for every website. Although the scale at which Amazon handles the website request is much greater than pCloud, pCloud static hosting is great for up to a thousand requests.

    If you want to share huge files, pCloud’s Public Folder is the best in the world. It’s easy, intuitive, and very convenient. But you have to acquire the address from the web browser.

    I just wish that you can can get the link directly from right-clicking the file, similar to what you could do with mountain duck when getting addresses from google apis, blackblaze B2, microsoft azure or amazon S3.

    Get the pCloud if you can. It’s really so much more than just a cloud storage.

  13. Correct the first sentence in your review from “cold” to “cloud”:

    “This updated review takes a look at Koofr, a ‘cold’ storage service that’s fast, secure and great for file sharing and collaboration.”
