Unlock PDF: remove the password
Many PDFs, from bank statements to payslips and course material, block printing or copying, or ask for a password every time you open them. Restriction-only files are unlocked straight away; if the PDF asks for a password to open, type it once and you get a copy that opens without one. This tool can’t crack a password you don’t know. Everything runs in your browser, so the file and the password never leave your device.
How it works
- Drop one or more locked PDFs here.
- If a file asks for its open password, type it and press Unlock. Print and copy restrictions need nothing.
- Download the unlocked PDF, or check it first with Preview.
FAQ
Can it unlock a PDF if I don’t know the password?
Only if the password just restricts printing, copying or editing: that kind of protection comes off without it. If the PDF won’t open without a password, you have to know it. Modern PDFs use AES encryption, and guessing an unknown password is not realistic, so we don’t pretend to.
What’s the difference between the two PDF passwords?
The open password (user password) is needed to view the file at all. The permissions password (owner password) only stops you from printing, copying text or editing, and any PDF reader can open the file without it. This tool removes both: the second one automatically, the first one once you type it.
Is it allowed to remove a PDF password?
Removing the protection from your own documents, like statements, invoices or payslips that a sender locked, is normal. Don’t use it to get around restrictions on files you don’t have the right to copy or edit; that’s your responsibility.
Does anything else in the PDF change?
No. Text, images, links, bookmarks and form fields stay exactly as they were, and nothing is re-compressed. Only the encryption is taken out. One catch: a digital signature in the file will show as invalid afterwards, because the file’s bytes have changed.
Are my PDF and password uploaded?
No. The unlocking runs on your device with qpdf, an open-source PDF tool, compiled for the browser. Neither the file nor the password is sent anywhere. On phones, very large PDFs (over about 150 MB) may run out of memory.
