How to remove a password from a PDF
Updated 3 min readBy Total PDF Tools
Quick answer
To remove a password from a PDF you can open, use Unlock PDF: add the file, type the password once and click Unlock. The tool decrypts the PDF in your browser and saves a copy without the password, so you can open, merge, edit or compress it freely. It works with AES-256, AES-128 and RC4 encryption. It does not crack or guess forgotten passwords.

Click Unlock. The file is decrypted locally with qpdf running in your browser.

Download the unlocked copy
Save the new PDF. Your original protected file is not changed.
Why unlock a PDF you already have access to
Bank statements, payslips and utility bills often arrive password protected. Typing the password every time gets tedious, and many tools can't merge, split or compress encrypted files. Unlocking your own copy removes that friction.
What Unlock PDF can't do
Unlock PDF only removes a password you already know. It doesn't crack, guess or bypass passwords, and no legitimate tool can open a properly AES-256-encrypted PDF without the password. Only unlock documents you own or are allowed to modify.
Frequently asked questions
I forgot the PDF password. Can you open it?
No. The tool needs the correct password. Ask the sender for the password or for an unprotected copy.
Is the password sent anywhere?
No. Decryption runs in your browser; neither the file nor the password leaves your device.
Can I add a new password afterwards?
Yes. Use Protect PDF on the unlocked copy to set a new password.
