A password on a PDF is useful until the file becomes one you open ten times a day. Removing it leaves you with a normal copy that opens straight away and works with every editing tool.
Before you start
Only unlock files that are yours or that you have permission to change. This guide assumes you know the password. If you don't, unlocking isn't possible with this tool, and no reputable service can promise to guess it for you.
How to remove the password
- Open Unlock PDF.
- Upload the protected PDF (up to 50 MB).
- Enter the current password.
- Download the unlocked copy and open it to confirm it no longer asks for a password.
Your original file stays protected, which is worth keeping as a backup.
When unlocking helps
- Editing. Most editors and converters can't open a file they can't read. Unlock first, then use Edit PDF, PDF to Word or Extract Text.
- Merging and splitting. Combine or cut a document with Merge PDF and Split PDF after unlocking.
- Long-term storage. A password you lose in five years makes an archived file useless.
If you forgot the password
Try the places it might be: an email from whoever sent the file, a password manager, or a note from when the document was created. Passwords are often based on something predictable that the sender mentioned, such as an account number, so re-read the message that came with the file. If none of that works, ask the person or organisation that created the PDF for a fresh copy. It is the only reliable route.
After you unlock
If the document still needs protection when it is shared, add a new password with Protect PDF. Our guide to choosing a strong password explains how.
Handling passwords sensibly
Unlocking creates a copy with no protection, so treat that copy with care. Don't email it to people who shouldn't see the contents, store it somewhere shared, or leave it in your downloads folder. Delete it when you have finished, or protect it again with a fresh password using Protect PDF. When you send the original protected file to someone, share the password by a different route from the file itself.
Frequently Asked Questions
Can you remove a password I don't know?
No. You need to provide the current password.
Is there a difference between an open password and a permissions password?
Yes. An open password stops the file opening. A permissions password restricts actions such as printing or copying. Unlock PDF is designed for files you can open with a password you have.
Does unlocking change the content?
No. Only the protection is removed.
Is it legal to unlock a PDF?
Removing the password from your own file is fine. Bypassing protection on someone else's document without permission can break the law or licence terms.
