How to Remove a Password from a PDF

Tired of typing a password every time you open a PDF you own? You can remove the password permanently. KOIAE's Unlock PDF tool takes the protection off a PDF so you can open and edit it freely — only ever use it on files you have the right to.
How to remove a password from a PDF
- Open the Unlock PDF tool. Go to the KOIAE Unlock PDF page.
- Upload the protected PDF. Drag and drop the password-protected file.
- Enter the password. Type the current password once so KOIAE can remove it.
- Download the unlocked PDF. Download a copy with no password required.
Tips for the best results
- You need to know the current password — this is not a password cracker.
- Only unlock PDFs you own or have permission to modify.
- Keep the unlocked copy secure since it no longer requires a password.
