Unlock PDF

Upload one PDF to remove owner permission restrictions, or enter the known open password to decrypt a password-protected PDF.

We do not crack or guess passwords. If the PDF requires a password, you need to provide the correct one.

Removes permission restrictions

If a PDF opens without a password but blocks printing, copying, or editing, we create a new unrestricted copy when the file allows it.

Secure processing

Files are processed on our servers using temporary files that are cleaned up after processing. We do not read your document contents.

Upload the locked PDF by clicking the upload area or dragging the file into it.
