Cryptomator for Mac download

Keep your cloud documents private

Cryptomator is a no-cost, open-source tool that encrypts files on your device before they are synced to cloud storage. It runs on multiple operating systems and works alongside popular cloud providers so your sensitive files stay unreadable to anyone who doesn't have your key. Users store items inside encrypted “vaults,” making it a practical solution for people who prioritize privacy and data protection.

What it does and how it feels to use

The app provides an intuitive interface that makes encrypting and accessing files straightforward. Once a vault is created, you interact with it like a normal folder while Cryptomator handles encryption and decryption automatically in the background. Cross-platform availability — including macOS support — means you can work with your protected data on desktop and mobile devices with minimal friction.

Key advantages

Strong, modern encryption standards protect files before they ever leave your machine.
Simple vault-based workflow lets you organize encrypted content just like regular folders.
Compatibility with many cloud services ensures broad interoperability across platforms.
Being open-source offers transparency and the ability for independent review of its security.

How it fits into a secure cloud strategy

Use Cryptomator as the client-side encryption layer in front of whatever cloud provider you prefer. Because encryption is performed locally, the cloud service only stores ciphertext — not readable files. This reduces the trust you must place in the storage provider while retaining the convenience of cloud synchronization.

Alternatives and pricing notes
