Koofr is a very secure storage service that seems predominantly aimed at keeping small files and sharing them. It covers this very well, and is fast, to boot, but third-party applications seem to have fallen by the wayside. Read our full Koofr review for all the details on this decent service.
Free plan available
Koofr is based in Slovenia and its name sounds a lot like a local word for a small suitcase. True enough, it doesn’t offer a lot of storage space like some of the big names in our best cloud storage piece do, but it’s still a capable service. To see what it has to offer, we’re going to take an in-depth look at it in this Koofr review.
Cloud storage lets you upload your content to to the cloud to clear your hard drive and collaborate with others. Koofr isn’t good for the latter, so you should refer to our best cloud storage for collaboration piece. If you can’t find one that fits your needs there, read our comparison of the best cloud services for more suggestions.
Koofr has fast speeds, capable sharing options and offers a good user experience. If that intrigues you, stick with us as we discuss its capabilities in the sections below.

Besides storing your files, services often have interesting and novel features that complement them. Koofr has a Chrome extension that allows you to save useful links, webpages, pictures and text from the web with one click.
You can integrate your existing cloud storage accounts, including Dropbox, Google Drive, Amazon Drive and OneDrive, to access your content through a single interface. If you’re not familiar with those services, check out our OneDrive review to learn more.
You can preview photos and Microsoft Office documents (.doc, .xls and .ppt), .pdf files and play some types of video files without downloading them. If you want to edit documents, you have to do it outside of Koofr because it doesn’t integrate with Google Office Suite, Microsoft Office or Zoho Office Suite.
There is no photo editing capability. If you need to do that online, read our best photo management piece for several options you can use.
A slick music player plays your audio files, but doesn’t enable you to create playlists or add songs to the queue. If you need those features, read our best cloud storage for music article.
A note-taking app is also missing. If you need one, you can refer to our best note-taking apps article. Evernote, one of the most popular note-taking apps is our top-pick on it, followed by OneNote and Google Keep. If you want the details read our Evernote review. Still, you can create a plain text file using the web interface if you’re in a pinch.
Local folders allow you to access and share files from your computer to another device without transferring anything to Koofr. The computer must be online for that to work, though.
Koofr has good plan flexibility because it offers six plans to choose from. Some services, like Dropbox, only offer one or two plans. Still, Dropbox has some redeeming qualities which you can read about in our Dropbox review.
The first plan, Starter, is free and offers 2GB of storage space. That’s a tiny amount but enough to test the service.
The paid plans are named after shirt sizes, so the first tier is, of course, S. For 57 cents per month, you get 10GB of storage space. M costs $1.14 per month for 25GB. Subscribing to the L plan costs $2.28 per month and gives you 100GB. XL gives you 250GB for $4.55 per month and, finally, XXL costs $11.38 per month for 1TB of space.
The plans are a far cry from the best value deals on the market. You can get more space for less by subscribing to Sync.com or pCloud.
Sync.com offers 2TB for $96 per year, but you can’t pay per month. You can subscribe to pCloud by paying a monthly or annual rate, though. For $9.99 per month or $95.88 a year, pCloud provides 2TB of space. If you’re interested, read our Sync.com review and pCloud review.
The web interface is clear and has lots of negative space, which makes it easy to find what you’re looking for. Contrasting colors bring into focus the most important operations.
It work fast and feels like you’re working with a desktop app. The navigation menu is on the left. In the upper right, you can switch between a list or tile view or access your account settings. There’s also a bookmark button that lets you tag folders for faster access and a share button that lets you share content with others.
The desktop client follows the common sync model, using a sync folder and system tray icon. The icon lets you access preferences and open your sync folder without going through the files manager app. The menu on the left lets you navigate the app without a hitch, while the central part of the app shows the contents of the menu. The button in the lower left opens the web interface.
Anything you put in the cloud will get downloaded to the sync folder and vice versa. When you copy a file or folder to your Koofr sync folder it automatically starts to sync to the cloud. The progress bar appears on the bottom, but it’s confusing because it doesn’t show the progress of your upload or the time remaining.
Koofr adds a shortcut to your desktop, too, so you can access your sync folder using it. The desktop app is available for Windows, macOS and Linux. If you’re shopping for services that are good for Linux, read our best cloud storage for Linux, piece.
The smartphone app is available for iOS and Android. It’s straightforward to use and the interface is clear and attractive.
Once you log in, you will see a menu with the same options as the web app. It does have the additional option to use files offline, though. You can upload existing media and new photos and videos can be uploaded automatically. If you’re on a limited plan, you can restrict uploads so that they only occur when you’re using a WiFi network.
You can’t sync folders, but you can copy files and folders by right-clicking and selecting “add to Koofr.” That will copy them to the Koofr sync folder and sync them to the cloud.
While on the free plan there’s no selective sync to turn off sync for specific folders or files, there’s an option to enable the Koofr network drive. Or, alternatively, you could pay for one of Koofr’s paid plans if selective sync is a deal breaker for you. A network drive only stores files in the cloud and lets you preview them on your computer without using hard drive space.
You can also enable sync icons that will let you know the status of your files and folders in Koofr’s sync folder. You can find more services that are good for syncing in our best cloud storage with sync article.
Share allows you to share with users in the app. Non-members will be invited to join when added.
You can share links to Facebook, Twitter, Reddit and Tumblr. That said, you can’t password protect links when sharing to social media websites. You can set links to expire in one hour, day or week, though. Unlike many services, Koofr enables those content control features for free users.
If you aim to share a lot, read our best cloud storage for sharing article.
To share a folder, you have to invite people by entering their email. When doing so, you can give them one or more permissions: “can comment (and see comments),” “can modify,” “can create download links,” “can create upload links” and “can manage shares.”
Koofr has a page that shows which folders you’ve shared and with whom, which is useful for keeping track if you share often.
Our tests showed that it takes around 23 minutes on average to upload a 1GB zipped folder. We connected over WiFi in Belgrade, Serbia with an upload speed of 6 megabits per second and a download speed of 102 Mbps.
The upload time is equal to the theoretical time it takes to transfer a 1GB folder, so we can assume you’ll experience similar speeds if you’re close Koofr’s servers in Germany.
Upload speed is a bigger factor when collaborating on files that have already been uploaded. Instead of uploading the whole file after you modify it, block-level sync can transfer only the portion that has changed, which reduces upload time significantly.
Koofr doesn’t use block-level sync. We know because we uploaded files after a slight modification and they didn’t upload any faster. A representative said that’s because they replace your content with an encrypted version. On top of that, Koofr doesn’t provide apps that enhance collaboration.
Migrating your files online is a risk without proper security. You can become a target for viruses, ransomware, man-in-the-middle attacks or someone trying to steal your password. To prevent those, cloud storage services should offer two-factor authentication to stop unauthorized access to your account, employ at-rest and in-transit encryptions and the TLS protocol to protect your data in transit. The best protection for your privacy is private, end-to-end encryption, which keeps anyone but you from reading your files.
As confirmed by a Koofr representative, once files reach the provider’s servers, it encrypts them using server-side encryption with the AES 256-bit algorithm which is one of the strongest.
You can turn on two-factor authentication to protect your credentials in the account settings, as well as “mandatory password protection.”
Koofr’s ISO 27001-certified data centers are located in the EU, which means the company has to comply with the laws enforced there. It employs redundant or backup power supplies, redundant data communication connections, environmental controls (e.g., air conditioning and fire suppression) and security devices, too.
Once your files reach a server, Koofr copies them to at least three physically separate locations. The metadata and content are kept on separate layers or even on completely separate servers. With that setup, nobody can use your metadata to figure out the location of your content on its servers. On-site technicians work around the clock to keep the system operating at full capacity.
There’s an FAQ that could be more detailed and include screenshots. There’s also a “contact us” form where you can ask questions. Telephone, chat support and user forums aren’t available, though.
Still, we asked a question via the contact form and received a response within one hour. That said, we can’t be sure how long support would take to answer questions from someone on the other side of the world.
Koofr doesn’t offer third-party integrations that drive collaboration, strong support infrastructure, block-level sync or good value subscription plans.
Still, it’s a decent service that has quality sharing capabilities, lets free users protect their shares with content control options and connects with other cloud storage services and shows from them in one interface.
On top of that, its upload speed is fast and security is tight. It safeguards your files using TLS/SSL, places them in secure data centers and complies with GDPR to protect your privacy. All that is wrapped in a streamlined and enjoyable user experience.
