QuickMergeUnlock a PDF and Remove Its Password
Short answer: To remove the password from a PDF you own, enter the current password and download a decrypted copy. QuickMerge performs the decryption in your browser without uploading the file or password.
Remove the password from a PDF you own so you stop retyping it every time the file opens. Decryption runs through the qpdf engine inside your browser, so neither the document nor the password is uploaded. You do need the current password — this is a convenience tool for your own files, not a cracker.

Stop Retyping the Password on a PDF You Own
Bank statements, payslips, and insurance documents often arrive password-protected — sensible in transit, maddening in your own archive. If you know the password, this tool removes it: the PDF is decrypted by the open-source qpdf engine compiled to WebAssembly, running entirely in your browser, and you download a copy that opens without a prompt.
To be clear about what this is not: it cannot crack, guess, or bypass a password you don't know. Decryption requires the correct password — that is how real encryption works, and any tool claiming otherwise is either lying or attacking weak legacy encryption. Everything runs on your device via open-source browser libraries — your file is never uploaded. You can verify it yourself.

What to do with the result
- compress the unlocked file — now that tools can read it.
- combine it with other documents — encrypted files cannot be merged.
- apply a new password — if you only wanted to change the old one.

Frequently Asked Questions
No. AES-encrypted PDFs are cryptographically locked; without the password the content is unreadable, full stop. This tool is for removing a password you know and are tired of retyping.
Removing protection from documents you own or are authorized to use (your own statements, your company's files) is normal document management. Don't use it on documents you have no rights to.
No. The password is passed to the qpdf engine inside your browser's memory and is gone when you close the tab. Neither the file nor the password ever leaves your device.
Decryption simply fails and you get a clear error — nothing is damaged, and you can try again. The original file is never modified.
Load the file, enter the password you already use to open it, and download the decrypted copy. Both the file and the password stay on your device.
No. Decryption requires the password, and this tool cannot guess or bypass it.
No. Decryption runs in your browser through qpdf compiled to WebAssembly, so neither the document nor the password is transmitted. You can verify that with the method on the proof page.
It carries permission restrictions rather than an open password. Those are reader-enforced flags, separate from the encryption that stops a file opening at all.
Yes — apply a new password once you are done, with AES-256 encryption.
Load the document above, type the password you currently use to open it, and download the decrypted copy. The file and the password are both processed on your device — qpdf runs as WebAssembly inside the page — so neither is transmitted anywhere.
Not if the security is a real open password: the content is encrypted and the password is the key. If the document opens but refuses to print or copy, that is an owner restriction rather than encryption, and it is a much weaker protection — but recovering an open password you never had is not something any honest tool offers.
The copy you download here has the encryption removed for good; it will never ask again. Your original file is untouched, so if you want the protected version gone, delete it yourself once you have checked the new copy opens.
It carries permission flags — the owner password case — rather than an open password. Those are enforced by whichever reader you are using and plenty of software ignores them entirely, which is why the same file often prints fine from a different application.
No. Decryption happens in your browser through qpdf compiled to WebAssembly, so the password is used locally and discarded when the tab closes. Nothing about the document or the password reaches a server, and you can verify that with the method on the proof of privacy page.
Yes — apply a new password with AES-256 encryption once you are done. That is the usual pattern: decrypt to work on the file, then re-protect before it leaves your hands. Record the new password somewhere durable, because there is no recovery route.
Remove a password only when you are authorised to do so
This tool is for documents you own or are permitted to modify, when you already know the password. It is not a password-cracking or access-bypass service.
Why create an unlocked copy?
An unlocked working copy can help with an approved archive migration, an internal accessibility workflow or a document that no longer needs transport protection. Keep the protected original until the new file has been checked and stored in an appropriately controlled location.
Understand what changes
Removing the open password does not erase visible watermarks, redact content or guarantee that every permission flag is removed. Rebuilding a secured PDF may invalidate digital signatures. If the signature is legally important, preserve the original and consult the issuing workflow.
Handle the result carefully
The unlocked download is easier for anyone with file access to open. Move it to approved storage, restrict sharing and delete temporary copies according to your organisation’s policy. QuickMerge does not retain a server copy that can be recovered later.

This removes a password you know; it does not break one you do not
The distinction is absolute, and worth stating plainly before you spend time on a file that cannot be opened.
You must be able to open the document already
Decryption needs the password. If you do not have it, no setting here recovers the file, and any site promising otherwise for a strong password is either failing or lying. AES-256 without the key is not a solvable problem.
Owner restrictions are a different thing
A PDF can be openable but restricted from printing or copying. Those flags are enforced by the reader rather than by encryption, and removing them is a much weaker operation than decrypting a file.
Only unlock what you are entitled to
Removing protection from documents you do not own or have no right to access is not something this tool makes legitimate. The intended use is your own files, and files you have been given the password for.
Why some protected PDFs open and others do not
A PDF can be locked in two quite different ways, and almost every confused search about removing PDF password protection comes down to not knowing which one is in front of you.
The user password stops the file opening
This is the one that produces a password prompt before you see a single page. It is real cryptography — AES-256 on anything produced this decade — and the document is genuinely unreadable without the key. To delete a password of this kind you have to supply it. Enter it above and download a copy with the encryption removed, and the file opens directly from then on.
The owner password only restricts what you may do
This one lets the document open normally but marks it as not-to-be-printed, not-to-be-copied or not-to-be-edited. Those flags are honoured by the reader rather than enforced by encryption, which is why a PDF can refuse to print in one application and print without complaint in another. Removing them is a much weaker operation than decryption, and it is why "how can I print a PDF that is secured" so often turns out to have nothing to do with a password at all.
Nothing here recovers a password you never had
If you cannot open the document, this page cannot help and neither can anything else that is telling the truth. A modern PDF without its key is not a puzzle with a shortcut; it is arithmetic that does not have a solution in any useful amount of time. Sites promising to unlock a PDF without the password either work only on the owner-password case above, or are collecting your file. Ours will not accept a document it cannot decrypt.
Removing protection is not the same as it never having been there
The decrypted copy you download is an ordinary unprotected PDF, so treat it accordingly — it is now readable by anyone who gets hold of it. If the document is sensitive and you only wanted to stop retyping the password on your own machine, keep the decrypted copy local and re-apply a password before it goes to anyone else.
