Koofr

Overview

Koofr is a cloud storage service for keeping files, syncing computers and connecting Dropbox, Google Drive and OneDrive accounts. It suits people who want those services searchable alongside their Koofr files, with mobile backup and desktop sync in the same offering. Its broad device support and security options are compelling, but the right plan depends on storage, sharing traffic and external-cloud connection limits.

Key features

Koofr stores and organizes files without individual file-size or file-type limits, and includes file versioning. That flexibility is useful for varied libraries and large files, though storage capacity still depends on the plan. Deleted files can be recovered for up to 30 days without counting against storage; the free plan has a shorter seven-day retention window.

Connections to Dropbox, Google Drive and OneDrive let users search those accounts through Koofr. Paid tiers include between 9 and 30 external cloud connections, while the free plan's connection allowance is not included in its plan details. Desktop apps provide unlimited two-way synchronization on Windows, macOS and Linux, and Koofr automatically backs up mobile media. Meta's transfer tool can bring over Facebook and Instagram media; Microsoft Office integration supports creating, viewing and editing Office documents.

Sharing works with people who do not have Koofr accounts, but public links and daily transfer quotas vary by plan. For security, files are transferred over TLS/SSL, encrypted on Koofr's servers and stored in at least three physical locations. Koofr says its servers are in Germany in ISO 27001-certified data centers and that it complies with GDPR. Koofr Vault adds open-source, client-side, zero-knowledge encryption, and two-factor options include TOTP apps and FIDO2 passkeys.

Pricing

Koofr is freemium. The free plan costs nothing and lasts forever, with 10 GB, seven-day deleted-file retention, up to 10 public links and 50 GB of daily public transfer. It is a useful starting point, but the limited retention and transfer allowance make it less suited to frequent sharing.

Paid subscriptions are currently available only yearly, although prices are stated per month. Each paid tier adds 10 GB of free space to its listed storage allowance:

S is the lowest-cost paid tier for users who need more daily sharing transfer and external connections but not more listed storage than the free plan. M and L scale storage while retaining the same 200 GB daily transfer and nine connections. XL through XXL raise transfer and connection allowances for larger libraries; XXXL and 5XXL suit users needing terabytes and up to 30 connections. Crate is the option for 10 TB or more. The plan details give no paid-plan public-link count or deleted-file retention period, so the free-plan caps should not be assumed to apply to paid tiers.

Platforms

Koofr is available on Android, iOS, Linux, macOS, Windows and the web, with a browser extension also supported. Desktop downloads are free for Windows, macOS and Linux. That range makes it practical for people moving between computers and phones, while the listed platform set does not include an API or self-hosted option.

Who it's for

Koofr is a strong fit for individuals who want one place to search connected cloud accounts, back up mobile media and synchronize computers, especially when client-side encryption matters. Its multiple storage tiers cover personal libraries from 10 GB to 5 TB and beyond. People whose main need is high-volume public sharing should compare daily transfer limits carefully, and organizations seeking seat-based pricing should note that these plans are expressed in storage and connection quotas rather than user seats.

Pros and cons

• Pro: Search across Dropbox, Google Drive and OneDrive from Koofr, reducing the friction of keeping files across services.

Verdict

Look elsewhere if you need monthly paid billing, a seat-based team plan or more daily public transfer than your Koofr tier allows.
