Remove a PDF Password — Free Online Tool
Take the password off a PDF you can already open — this removes a password you know, it does not recover one you have forgotten.
About Unlock PDF
Two different documents send people to a page like this. One asks for a password every time it opens. The other opens straight away and then refuses to print, or will not let you select a line of text out of it. This tool takes the encryption off both, using qpdf compiled to WebAssembly and run in your tab — but it is worth being exact about which one you have. If the document prompts for a password, you have to know that password. Type it in and you get back a copy with no password on it. If you do not know it, this page cannot help you, and neither can any honest tool: removing a password you know is not password recovery, and this is not a password recovery tool. There is no guessing, no dictionary, no queue that emails you a result later. A wrong password is reported as a wrong password — qpdf says so, the tool passes that on, and no file is written rather than one that is half decrypted. The second case is the interesting one. A PDF that opens without a prompt but will not print is carrying restrictions and an owner password only, and that comes off without you typing anything at all. This is not a trick, and it is not a weakness in this tool: it is what PDF permission flags are. They record what the author intends to allow, and any tool that can read the file can clear them. If that is a surprise, PDF Permissions is the page that explains it, and it is worth reading before you rely on those flags for anything. Removing the password removes those restrictions with it, because both live in the same encryption dictionary. The document is checked before anything runs, so the tool knows which of the three states your file is in — not encrypted, restricted only, or password required — and tells you which. That matters more than it sounds: decrypting a file that was never encrypted succeeds silently, so without that check the tool would happily report a successful unlock of nothing. Everything runs in your browser; the encrypted document and the password you type both stay on your machine.
Questions
I forgot the password — can this open my file?
No. This tool decrypts a PDF using the password you type in; it does not search for one. There is no guessing, no dictionary and no queue that emails you a result later. If the password is genuinely lost, no tool on this site — and no honest tool anywhere — will get the file open for you. What it will do is take a document you can already open and hand you back a copy with the encryption removed.
My PDF opens without asking for anything but will not let me print. Will this help?
Yes, and you will not have to type anything. A document that opens without a prompt but refuses to print is carrying restrictions and an owner password only, and that comes off with no password from you at all. That is not a trick this tool plays — it is what PDF permission flags are, and it is the plainest demonstration that they were never a lock. PDF Permissions is the page that explains what they can and cannot do.
Does this remove the printing and copying restrictions too?
Yes. The permission flags live inside the same encryption dictionary as the password, so decrypting the document clears them together. There is no way to remove one and keep the other, and there would be little point: a reader that would honour those flags is one that would have asked for the password.
What happens if I type the wrong password?
You are told the password was wrong, and no file is produced. qpdf reports an invalid password and stops before writing anything, so you never get a half-decrypted document that looks like it worked. Try again with the right password; nothing about the file has changed.
What if the PDF turns out not to be protected at all?
The tool checks first and says so. That check is there for a specific reason: decrypting a document that was never encrypted succeeds quietly, so without it the page would report a successful unlock of a file that had nothing to unlock. Three states are distinguished before anything runs — not encrypted, restricted only, and password required — and you are told which one you have.
Is my file uploaded to a server?
No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
