Text & File Encryptor

Password-based AES-256-GCM encryption for text and files. Keys are derived with PBKDF2 (150,000 iterations) and everything runs in your browser via the Web Crypto API. Nothing is uploaded.

Output appears here.
Drop a file to encrypt
or click to browse (any type, any size)
Files never leave your browser

Decrypt mode expects a .enc file produced by this tool.

100% local. Encryption and decryption happen entirely on your device. Your password is never stored or sent anywhere, and the key is derived fresh each time with PBKDF2 (150,000 iterations, SHA-256) using a random salt. AES-256-GCM also authenticates the data, so a wrong password or tampered ciphertext fails safely. There is no recovery, if you lose the password, the data is unrecoverable.

About Text & File Encryptor

Text & File Encryptor is a free, private browser tool by Digital Heroes. It uses AES-256-GCM with a password you choose to encrypt or decrypt text snippets and files of any size. Keys are derived with PBKDF2 and a random salt every time, so no two encryptions produce the same output even with the same password. Because everything runs entirely in your browser, your data is never uploaded to a server. No sign-up, no installation, no limits.

What you can do

How to use Text & File Encryptor

  1. Choose Text or File mode at the top, then choose Encrypt or Decrypt.
  2. Type a strong password in the password field. The strength meter updates as you type.
  3. In Text mode, paste your message (or Base64 ciphertext) and click Encrypt or Decrypt. Copy the result with the Copy button.
  4. In File mode, drop any file onto the drop zone (or click to browse), then click Encrypt & download. Your browser saves an .enc file. To reverse this, switch to Decrypt mode, drop the .enc file, and download the restored original.
  5. Your password is never stored or sent. Keep it safe, because there is no recovery option.
