How to Unlock a PDF
Remove the password from a PDF you own — free, in your browser, no upload.
Unlocking a PDF you own
A password on a PDF is a lock, and like any lock it can become a problem for the person who owns the key. You set a password months ago and now you need the file in a reader that does not ask for it. You need to merge a protected file, or print it on a machine that cannot enter a password. Or you simply want a copy without the lock, for your own archive. Unlocking removes the password — but only if you know it.
This tool needs the correct password, and there is no way around that. It does not guess passwords, it does not recover a forgotten password, and if the password is wrong it says so. That is the honest rule of every real unlocker: a password that could be guessed by a tool would not be a password at all. Give the right password, and the tool produces a copy of the file without the lock. You can unlock up to 20 files at once, 100 MB in total, all with the same password.
The honest limit is what the unlocked file is made of. It is built from images of the pages — so the text in the output can no longer be selected or searched. For reading, printing, and merging, that does not matter at all: the pages look the same, and they are rendered at high resolution, so print stays sharp. But for a document you still need to search — a long report, a contract you grep through — the unlocked copy is the wrong one to keep. Keep the original locked file as your searchable copy, and use the unlocked file for the job that needed it.
A few practical tips. Unlock a copy, not your only file, and keep the locked original somewhere safe — especially if you no longer remember where the password is written down. If the file has to be shared, consider whether it should stay locked: removing a password is easy, and once the unlocked copy is out, the lock is gone for everyone who has it. And if you forgot the password entirely, no tool can help — not this one, and not any honest one. That is the point of a password.
It also helps to know why the unlocked file is made from images. A locked PDF stores its pages encrypted, and the only honest way to rebuild the file without the encryption is to render each page and write a new file from those renderings. That is why the text cannot be selected afterwards: the new file holds pictures of the pages, not the characters. For reading, printing, and merging, a picture of a page is exactly as good as the page itself — the words look the same, and the print is sharp. For searching, it is not: a picture has no text to search. If you need both — a file without a password and a file you can search — unlock a copy for the job at hand and keep the locked original as the searchable one, with the password stored in a password manager.
And a warning about the password itself. The password is typed on your device and never leaves it — it is not uploaded, not stored, and not sent anywhere. That is why the tool cannot recover it: there is no copy of it anywhere to recover from. Write the password down somewhere safe before you protect a file, and store it in a password manager rather than in a note on the file itself. A password that only exists in your head is a password that will one day be forgotten, and a forgotten password means a locked file forever.
Everything runs in your browser. Your file and your password are never uploaded to a server — the password never leaves your device. There is no account, no daily limit, and no watermark. Open the tool, drop your locked PDF, type the password, and download the unlocked copy.

Frequently asked questions
I forgot the password. Can the tool recover it?
No. There is no way to recover a forgotten password — the tool does not guess passwords. If the password is wrong, the tool says so.
Is the text still selectable after unlocking?
No. The unlocked PDF is made from images of the pages, so the text can no longer be selected or searched. For reading, printing, and merging that does not matter.
What if I still need to search the text?
Keep the original locked file as your searchable copy. The unlocked file is for reading, printing, and merging.
Will the print quality suffer?
No. The pages are rendered at high resolution, so print stays sharp.
How many files can I unlock at once?
Up to 20 files, 100 MB in total, all with the same password. There is no daily limit.
