How to use Encrypt Files and Folders
- Choose your files.

- Download the encrypted .zip and open it with 7-Zip, WinZip or Decrypt files or folders. File names remain visible. Keep the password safe: OneKit cannot recover it.

Do my files leave my device?
No. Thanks to advanced file-processing technology, your files are processed directly on your device, inside your browser. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
