Remove a Password From a PDF
Remove a password from a PDF you can already open. Type the password once, and what comes back is the same document with the encryption taken off — useful when a bank statement or a payslip arrives locked and you need to merge it, print it, or stop typing the password every time you look at it. It cannot recover a password you do not have, and nothing here tries to.
Use this without the search next time. Prathom Workbench puts Prathom's tools in your toolbar.

How to use Unlock PDF
- 1
Add the PDF
Drop the locked file in or choose it from your computer. Nothing is read from it until you supply the password.
- 2
Type the password
The one that opens the document today. It is sent with the file, used once, and never written down anywhere.
- 3
Download the open copy
The result is the same PDF without encryption — same pages, same text layer, same links and form fields.
Two different things called "unlocking a PDF"
The phrase covers two situations that could not be further apart, and it is worth knowing which one you are in before looking for a tool.
You know the password and want it gone. A bank sends statements encrypted with your customer number. Payroll sends payslips locked with a date of birth. You can open the file, you just do not want to type it every time, and no other PDF tool will touch the document while it is encrypted. That is this page.
You do not know the password. That is not unlocking, it is breaking, and a properly encrypted PDF does not yield to it. Anything promising otherwise is either guessing common passwords, exploiting files that were never really protected, or lying.
How it works
The password is passed to qpdf, which decrypts the document and writes it out
without encryption. If the password is wrong, qpdf refuses and you are told so —
there is no second attempt, no list, and no fallback.
Nothing is re-rendered. The pages, text layer, links, form fields and bookmarks are the ones that were in the original, which is why the output is genuinely the same document rather than a picture of it.
Why other tools refuse an encrypted PDF
If you have tried to merge, split or convert a locked file and been told it is damaged, this is why. Encryption is applied to the whole document structure, so software that cannot supply a password cannot read the page tree either — it sees something it cannot parse and reports the nearest thing it has a message for.
Removing the password first is usually the entire fix, and everything that refused the file will then accept it.
What happens to your password
It is sent with the file, used for the one decryption call, and discarded when the request finishes. It is not logged, not stored, and not retained in any form. The uploaded PDF and the result are deleted within 30 minutes along with everything else that passes through the converter.
If a document is sensitive enough that even that is the wrong trade, qpdf is
free software and runs on your own machine in one command — that is the honest
alternative rather than a reassurance.
Examples
A bank statement that arrives locked
Banks and payroll systems commonly send statements encrypted with a customer number or a date of birth. Once you have opened it, keeping it locked in your own records serves nobody.
A locked file you need to merge
Most PDF tools, this site's included, cannot read an encrypted document at all. Removing the password first is what makes merging, splitting or converting possible.
Frequently asked questions
Can this open a PDF when I do not know the password?
No, and nothing else honest will either. This decrypts using the password you supply; there is no code path that guesses, tries a list, or attempts more than the one you typed. Without the correct password the file stays closed. If a site claims otherwise about a properly encrypted PDF, it is either wrong or describing something you should not be doing.
Is it legal to remove a password from my own PDF?
Removing protection from a document you are entitled to open is an ordinary thing to do — a bank statement encrypted with your own date of birth is the common case. What is a different matter entirely is defeating protection on a document you were not given access to. This tool only does the first, because it requires the password as input.
What happens to the password I type?
It travels with the file to our server, is passed to the decryption step, and is gone when the request ends. It is not written to a log, not stored in a database, and not kept in the browser. The file itself, and everything produced from it, is deleted within 30 minutes.
Does the document lose anything?
No. Decryption is not a re-render — the pages, the text layer, links, form fields, bookmarks and images all come across untouched. The only difference between the input and the output is that one is encrypted and the other is not. The file may get slightly smaller, because encryption adds overhead.

- What a PDF Password Actually Costs, in Bytes and in ProtectionPutting a password on a PDF costs almost nothing in size, which is the least interesting thing about it. The interesting part is that a PDF can carry two completely different kinds of password, and only one of them is protection.
- A Black Box Over the Text Removed Nothing At AllCovering words with a black rectangle is what every general-purpose PDF editor makes easy, and it is the single most common way confidential documents leak. The rectangle is drawn on top. The words are still underneath it, in the file, and any extractor will hand them back in full.
- Why PDF to Word Never Comes Out PerfectA PDF does not contain paragraphs. It contains characters at coordinates, in whatever order the program that made it happened to emit them. Everything a converter hands you above the level of a single character is a reconstruction, and knowing which parts were guessed tells you where to look first.
