Text & file encryptor. Locked before it leaves.

Password-encrypt text or any file with AES-256-GCM. Keys are derived fresh with PBKDF2, and everything runs in your browser via the Web Crypto API, nothing is uploaded, nothing is stored.

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.
§ 02 · what you can do

Everything a private encryptor should do.

  • Encrypt any text with a password and get a portable Base64 ciphertext you can copy and share.
  • Decrypt that Base64 back to plaintext instantly, in the same tab.
  • Encrypt any file, document, image, archive, any type or size, and download the protected .enc file.
  • Decrypt a .enc file back to its original format with the correct password.
  • Check password strength live as you type, with guidance on length, case, numbers and symbols.
  • Stay completely private: AES-256-GCM via Web Crypto, no uploads, no server, no account.
§ 03 · how to use it

Five steps, no keys to manage.

  1. Choose Text or File mode, then Encrypt or Decrypt.
  2. Type a strong password, 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 to save an .enc file. To reverse, switch to Decrypt and drop the .enc file.
  5. Keep your password safe, it is never stored or sent, and there is no recovery option.
§ 04 · faq

Frequently asked questions.

Is the Text & File Encryptor free?
Yes, completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Are my files uploaded anywhere?
No. The encryptor runs entirely in your browser on your own device using the Web Crypto API, so your text, files and password never leave your computer, nothing is uploaded to a server.
What encryption does it use?
AES-256-GCM, an authenticated cipher. Your password is turned into a key with PBKDF2 (150,000 iterations, SHA-256) using a fresh random salt each time, so the same text encrypted twice produces different output.
What happens if I forget the password?
There is no recovery. Because the password is never stored or sent anywhere, nobody, including us, can restore the data without it. Keep a copy of the password somewhere safe.
Does it work offline?
Yes, once the page has loaded, all encryption and decryption runs locally, so it keeps working without a connection.
