About this tool

Free client-side file encryption: AES-256-GCM + PBKDF2, .dte format, works offline, nothing uploaded. Wrong passwords fail safely. Client-Side File Encryptor runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • Client-Side File Encryptor is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
