Is Cloud Storage Really Safe? Cryptomator Encrypts Your Files

Platform: Windows, macOS, Linux
Program: Cryptomator Desktop

Uploading your files to the cloud provides great convenience. You can access your documents from different devices, back up your photos and share your files with others.

But there is an important question: How much control do you have over who can see the content of the files you upload to the cloud?

Cryptomator is a tool that helps you encrypt your files before sending them to cloud storage.

The basic logic of the program is to encrypt your files on your local device and then synchronize the resulting encrypted data with the storage you use.

For example, you keep your documents in a cloud folder. With Cryptomator, you can create an encrypted vault, place your files in it, and sync the encrypted content with supported cloud storage services.

This method makes it difficult for the cloud service to directly access the readable version of the files. However, issues such as the security of the account you use, malware on your device, and protection of your password remain important.

With Cryptomator you can:

• Creating an encrypted safe for sensitive documents.

• Encrypting files before uploading them to the cloud.

• Using an encrypted structure that also helps protect file and folder names.

• Accessing your encrypted safes on different operating systems.

• Creating an additional layer of security for business documents, personal records or private files.

For example, you want to store your identity documents, contracts or private work files in the cloud. Instead of uploading them directly in a readable format, you can keep them in an encrypted vault with Cryptomator.

Cryptomator's 1.19 series released in 2026; It includes security, accessibility and application improvements. The developer's article dated October 2, 2026 also explains why client-side encryption is important in cloud security.

There is an important detail here: You must keep the password and recovery information of the encrypted safe securely. Losing them can make it difficult or impossible to access your files.
