Koofr

Koofr is a cloud storage service for storing, organizing, accessing, and managing files. It works on the web and on Windows, macOS, Linux, iOS, and Android, with a browser extension also listed. The free plan includes 10 GB; paid plans start at €0.50/mo (annual). Koofr says it has no individual file-size or file-type limits. You can connect Dropbox, Google Drive, and OneDrive accounts and search them through Koofr. The service can automatically back up mobile media and offers two-way computer synchronization through its desktop app. It also supports sharing with people who do not have Koofr accounts, and deleted files can be recovered for up to 30 days. Security features include TLS/SSL transfers, encryption on Koofr servers, TOTP authentication apps, FIDO2 passkeys, and Koofr Vault, a client-side, zero-knowledge encrypted storage application. Koofr says its servers are in Germany in ISO 27001-certified data centers and that it complies with GDPR. The company was founded in 2013 and is headquartered in Ljubljana, Slovenia.

Koofr combines storage, cloud-account connections, sharing, backup, and desktop sync across several platforms. The free plan offers 10 GB, while paid plans start at €0.50/mo (annual).

Koofr suits people who want cloud storage across desktop and mobile platforms, with options to connect other cloud accounts. Its tools may also suit individuals, ISPs, and enterprises, which the company identifies among its users and customers.

Koofr is a cloud file service that combines its own storage with search across other major cloud accounts, device synchronisation and backup. It is a strong fit for people managing several services and devices rather than for anyone seeking storage alone. Its security controls and unusually flexible file handling are persuasive, but quotas for storage, links and connected accounts determine which tier makes sense.

Overview

Koofr provides tools to store, organise, access and manage files through web, desktop and mobile clients. It places no individual file-size or file-type limits, so large or mixed-format collections are not blocked by per-file rules. Capacity still depends on the subscription, and the free account offers 10 GB.

File versioning adds a useful safety net when documents change, while deleted files can be restored for up to 30 days without consuming storage during retention. Free accounts reduce that recovery period to seven days. Sharing can include people who do not use Koofr, making it practical for sending files outside your own account.

Key features

Koofr can connect Dropbox, Google Drive and OneDrive accounts and search those services from its interface. This is the service's clearest differentiator: it can reduce the need to remember where a file lives. Paid plans allow between nine and 30 external cloud connections, with the allowance increasing on higher tiers.

Its desktop application offers unlimited two-way synchronisation on Windows, macOS and Linux. Koofr also automatically backs up mobile media, covering a common phone-to-cloud task without making desktop synchronisation the only backup route. Meta's transfer tool supports moving Facebook and Instagram media, and Microsoft Office integration allows Office documents to be created, viewed and edited.

Security is layered rather than dependent on one feature. Transfers use TLS/SSL, files are encrypted on Koofr's servers and copies are stored in at least three physical locations. The company says its German data centres are ISO 27001-certified and that it complies with GDPR. TOTP authenticator apps and FIDO2 passkeys provide two-factor choices. Koofr Vault is an open-source, client-side, zero-knowledge encrypted storage application for files that need encryption before they reach the service.

Sharing limits matter for frequent publishers. Public links and daily transfer allowances vary by plan, so a free account can be adequate for occasional exchanges but restrictive for sustained distribution.

Pricing

Koofr uses a freemium structure. All paid subscriptions are currently available only as yearly subscriptions, despite prices being shown per month.

The Free plan suits a small personal archive or light sharing, but its shorter recovery period and 50 GB daily transfer cap limit it for active distribution. S is the lowest-cost paid step and keeps the same 10 GB base capacity while adding another 10 GB, higher transfer and nine connections. M and L are better when storage, rather than sharing, is the constraint. XL and above are aimed at larger libraries or link traffic; XXL and larger tiers make sense only when terabytes or many connected accounts justify the annual commitment. Crate is for requirements above 10 TB and uses custom pricing.

Platforms

Koofr supports Android, iOS, Windows, macOS, Linux and the web, with a browser extension also listed. Free desktop downloads cover Windows, macOS and Linux. That span suits households or individuals moving between desktop and mobile systems without narrowing the choice to one ecosystem.

Who it's for

Choose Koofr if you want one search point for Dropbox, Google Drive and OneDrive alongside your own files, plus automatic mobile-media backup and unlimited desktop synchronisation. It is also a good match for privacy-conscious users who value Vault, passkeys or authenticator-based two-factor security. People who only need a small, simple drive may find the connected-account and plan structure unnecessary, while heavy sharers should budget for a tier with a larger daily transfer allowance.

Pros and cons

Pros

• No individual file-size or file-type limits, which avoids arbitrary upload barriers.
• Search across Dropbox, Google Drive and OneDrive, reducing fragmented cloud storage.
• Unlimited two-way desktop sync and automatic mobile-media backup cover both computers and phones.
• Vault offers client-side, zero-knowledge encryption, with TOTP and FIDO2 options for account protection.
• Recipients do not need Koofr accounts, and deleted files can remain recoverable without using storage during retention.

Cons

• Paid plans require yearly subscriptions, so the low monthly figures do not provide a month-to-month option.
• The free plan has only 10 GB, seven-day recovery, 10 public links and 50 GB of daily public transfer.
• External-cloud connection allowances are tiered, and the largest capacities require substantially higher annual commitments.

Alternatives

For a broader comparison of sharing-focused services, see File Sharing Software; for storage-first choices, see Cloud Storage Services.

• Microsoft PowerPoint is the better choice when the priority is creating and editing presentations, with Android, iOS, macOS, web and Windows support.
• Google Drive suits users who want 15 GB of no-cost storage included with a Google Account.
• Internxt Drive is worth considering when publicly available, externally audited code and encrypted cloud storage are central requirements.
• Nutstore is oriented toward team plans with five-member minimums and per-member quotas.
• ownCloud is the alternative to consider when self-hosting is important.
• pCloud offers a free 10 GB tier and paid storage plans for users prioritising a straightforward storage account.
• SugarSync is another cross-platform synchronisation service with personal capacity tiers.
• Icedrive provides a free 10 GB plan and encrypted-storage options across desktop, mobile and web.

Verdict

Koofr is recommended for individuals who need storage, mobile backup, desktop sync and a searchable view of several existing cloud accounts in one place. Its strongest reasons to choose it are broad platform coverage, file-handling freedom and serious encryption options. Look elsewhere if you need monthly billing, a very large free allowance or a service without tiered sharing and external-connection limits.
