Remove PDF Password

Decrypt a PDF when you already know the open password.

Upload a password-protected PDF, enter the current open password, and download a copy without encryption. The original upload is not modified.

When to use this

  • You have the correct open password and need an unprotected file for further editing or conversion
  • For owner-only restrictions without an open password, unlock PDF may be enough

Limits

  • One PDF up to 10 MB
  • Wrong or unknown passwords are rejected — nothing is cracked
  • Only use on documents you are allowed to decrypt

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

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.
