Remove password protection from a PDF you can already open.
The Unlock PDF tool removes password protection from PDF files. It is intended for documents you own or have legitimate access to — for example, a salary slip or bank statement issued with an opening password that you would like to archive without it.
The output is a fully open PDF. For permission-protected files, the original content streams are preserved so text remains selectable. For open-password files, pages are re-rendered into images during decryption — the result is visually identical but text-as-image.
