A PDF encrypted with a password you set yourself years ago and have since forgotten has no "forgot password" recovery flow the way a website login does, and a document inherited from an old project where the original creator is long gone is just as stuck, while some PDFs aren't actually encrypted at all, they only carry an owner password restricting printing or copying, a weaker protection that never required knowing anything to remove in the first place. This tool removes password protection from a PDF, unlocking a file you have the right to access rather than bypassing security on someone else's protected document. Useful for recovering access to your own PDF after forgetting a password you set yourself, removing print or copy restrictions from a document that was never actually encrypted, or unlocking an old file inherited from a project where the original password is no longer available.
