Unlock PDF

Remove printing, copying, and editing restrictions from a PDF.

Upload a restricted PDF and download an unencrypted copy without owner limits on print, copy, or edit. If the file asks for a password to open, enter it.

Unlock vs remove password

  • Unlock — often enough when only owner restrictions apply (empty user password)
  • Remove password — always asks for the current open password before decrypting

Limits

  • One PDF up to 10 MB
  • Unknown passwords are not guessed or recovered
  • Use only on documents you are allowed to unlock

Passwords are used for the current job only and are not stored.

Security and privacy

  • Encryption at rest

    Files are encrypted during storage with AES-256-GCM using a unique key per file

  • Auto-deletion

    Uploaded and processed files are removed after the session ends

  • Temporary sessions

    Processing sessions expire automatically and are not kept as a permanent archive

  • Protected download links

    Downloads require a short-lived access token — not a public permanent URL

FAQ

Unlock removes owner restrictions such as printing limits and can work with an empty user password. Remove password always requires the current open password before decrypting.

Yes. Files are transferred over a secure connection, encrypted while stored on the server, and automatically deleted. Flimpa does not store documents permanently and does not use them to train models.
