Encrypt files with AES-256 directly in your browser
Upload any file, set a password, and encrypt it locally with AES-256. No upload to external servers.
AES-256 encryption
Uses WebCrypto with AES-256-GCM for strong client-side encryption.
Local processing only
Your file and password stay in your browser and are never sent to our servers.
Simple wizard flow

How file encryption works
Select a file, enter a password, and generate an encrypted output file that you can store or share safely.
Frequently asked questions
Is encryption really client-side?
Yes. Encryption runs in your browser via WebCrypto. No file upload is required.
Which algorithm is used?
AES-256-GCM is used, with a key derived from your password using PBKDF2-SHA-256.
Can I encrypt any file type?
Yes. The tool works with any file type because it encrypts raw file bytes.
Can I recover my file without password?
No. If the password is lost, the encrypted file cannot be decrypted.
