Download Cryptomator for Windows PC v1.19.3 for Windows PC

Cryptomator is open source client side encryption software from Skymatic GmbH that protects files before they reach cloud storage.

Features

• Client-side encryption means files are encrypted on your own computer before upload, so cloud providers and anyone who gains access to the synced folder see only encrypted data, never your readable documents.
• Each vault appears as a familiar virtual drive in Windows Explorer after unlocking, so you open, edit, and save files normally without manually encrypting or decrypting individual files every time.
• Filename encryption and an open source, independently audited codebase strengthen privacy beyond simple content encryption, hiding document names and allowing security researchers to verify how the protection actually works.
• Cryptomator works with Dropbox, Google Drive, OneDrive, and any folder-based sync service because it encrypts a normal folder, so you are not locked into a single proprietary cloud provider.
• Per-file encryption means changing one document only re-uploads that file's encrypted data, which keeps sync fast and efficient compared with a single large encrypted container that must upload again entirely.

Considerations

• If you lose or forget your vault password and recovery key, the encrypted files cannot be recovered by anyone, including Skymatic, because no backdoor or password reset exists by design.
• Working through a virtual drive can feel slower with thousands of small files, and sync errors are harder to diagnose because you are troubleshooting both Cryptomator and the cloud client.
• Sharing a single file with someone who does not use Cryptomator is inconvenient, since you must decrypt and send it separately rather than using the cloud provider's normal sharing link.

Is Cryptomator free on Windows?

Yes, the desktop version for Windows is free and open source under GPLv3. The mobile apps for Android and iOS are paid, which helps fund development of the project.

Which cloud services work with Cryptomator?

Cryptomator works with Dropbox, Google Drive, OneDrive, and any service that syncs a folder on your computer. The vault is just an encrypted folder, so it does not depend on a special provider integration.

What happens if I forget my vault password?

Your files cannot be recovered without the password or the recovery key shown when you create a vault. Store the recovery key somewhere safe and separate, because Cryptomator has no reset or backdoor by design.

How is Cryptomator different from a ZIP file with a password?

Cryptomator encrypts files individually inside a vault that behaves like a normal drive, so you can work live and sync only changed files. An encrypted ZIP must usually be recreated and re-uploaded as a whole after any change.

Is Cryptomator secure?

Cryptomator uses AES-256 encryption with scrypt key derivation and encrypts filenames as well as contents. Its code is open source and has been independently audited, though no software can protect data on an already compromised computer.
