Unlock a PDF

How it works

A locked PDF is not a normal PDF with a password attached to it. The pages themselves are encrypted: the text, the embedded fonts and the images are all stored as ciphertext, and the password is what produces the key that turns them back into a document. That is why a locked statement cannot be searched, printed to a file, or opened by anything that does not ask you first.

This tool decrypts every one of those pieces with the key your password produces, then writes the file back out with the encryption entry removed. The result is the same document. Same pages, same selectable text, same fonts, same size. Nothing is re-rendered and nothing is flattened into an image, so the copy you get back is as useful as the original was.

That last point is the difference between this and the trick most people already know. Opening a statement and choosing Print, then Save as PDF, does produce an unlocked file, because your viewer had already decrypted the document in order to show it to you. What comes out is a fresh photocopy rather than your file, and it quietly loses the bookmarks, the links, the form fields and the metadata on the way through.

Files that open but will not print

Some PDFs open without asking for anything, then refuse to print, or will not let you copy a line of text. Those files have a second kind of password, sometimes called the owner or permissions password, which does not lock the document at all. It sets a few flags that ask your viewer to disable printing, copying or editing, and the viewer chooses to obey them.

Drop one of those here and the tool will notice that it opens without a password and tell you so. There is nothing to type. Unlocking writes the same document back out without the flags, so it prints and copies like any other file.

You need the password

If a file asks for a password before it will show you anything, this removes that lock only once you type it. It does not open one you cannot, and there is nothing here that guesses, and no list of common passwords being tried in the background. If the password is genuinely gone, the content is gone with it, which is the entire purpose of encrypting a file in the first place.

If the file came from a bank, the password is usually printed in the email it arrived with, and it is usually built from something you already know: a date of birth written without separators, a customer number, or the last few digits of the account. It is worth checking for a space on the end if you copied it out of a message.

Where your file goes

Nowhere. The unlocking happens on your device, in the tab you are reading this in, and neither the file nor the password is sent anywhere. That matters more here than on the other tools: a statement and the password to it are the two halves of something worth stealing, and the only safe version of this tool is one that never has either.
