Unlock PDF

Remove a password you already know from a PDF, so you do not have to type it every time you open the file.

You need the password: this tool removes a password you know and cannot guess or crack one. Only unlock files you have the right to.

Quick answer

Choose the protected PDF, enter its password, and press Unlock to download a copy that opens without one. You need to know the password: this tool removes it but cannot guess or crack it. It works with PDFs protected by RC4 or AES, and it all runs in your browser, so your file and password are not sent anywhere.

How to use it

  1. Choose the protected PDF. The file stays on your device.
  2. Enter its password. The password you use to open it.
  3. Download. Press Unlock PDF to save a copy without a password.

Example

A bank statement you open often:

Input

statement.pdf (asks for a password)
Password: the one you already use

Output

statement-unlocked.pdf
Opens without a password. All pages are unchanged.

Common errors and how to fix them

That password is not correct
Check capitals, and any spaces copied by accident. Passwords must match exactly.
I do not know the password
This tool cannot help without it. Ask whoever sent you the file.

Frequently asked questions

Can this crack a PDF if I forgot the password?

No. It needs the correct password, as it uses it to decrypt the file. Good encryption has no shortcut.

Why remove a password at all?

To avoid typing it each time, to merge or edit the file, or to store it in a system that cannot read protected PDFs, such as a bank statement in your own records.

Is it legal to unlock a PDF?

Generally, if it is your own file or you have the right to use it without protection. Do not remove protection from documents you have no right to.

Is my password stored?

No. It is used in your browser for this one file and is gone when you leave the page.

Is the original file changed?

No. You get a new copy, and the protected original remains as it is.

Are my pages or quality changed?

No. The content is decrypted and saved again, with nothing re-rendered.

What about PDFs that open but will not print or copy?

Those have only permission limits. Some can be saved as unrestricted here if you have the right to do so, leaving the password box empty.

Why does it say the password is wrong?

Passwords are case-sensitive, and a space copied by accident counts. Bank PDFs often use a pattern, such as part of your name and date of birth, explained in the email.

What can I do with the file after unlocking it?

Anything your other tools can do with a normal PDF, such as Merge PDF or Split PDF, without being asked for a password.

Should I keep the unlocked copy?

Only somewhere safe, because anyone can now open it. To protect it again, use Protect PDF.
