What does Unlock PDF do?
It makes a copy of your PDF without its password, so you can open, print, copy text and edit it without being asked again.
Deleted right after unlocking
Your PDF and password are sent over a secure connection and deleted as soon as the unlocked file is ready.
Why use our Unlock PDF tool?

Each file is deleted right after unlocking, and the password is never saved.
Fast result

Nothing else changes
Pages, text and images stay exactly as they were.
Free to use
No sign-up, no watermark, no software to install.
Unlock PDF Online for Free
Use the DailyOnWeb Unlock PDF tool to remove the password from a PDF that you own. This is useful when you are tired of typing the same password, when you need to print or copy text from a locked file, or when you want to merge, edit or compress a protected PDF.
How to unlock a PDF
- Click Select PDF file, or drop your PDF on the page.
- Type the password if the PDF asks for one to open.
- Click Unlock PDF and wait a few seconds.
- Download your unlocked PDF. It is saved with -unlocked added to the name.
Two kinds of PDF protection
- An open password is needed to view the file at all. You must enter it to unlock the PDF.
- A permissions password does not stop you from reading the file, but blocks printing, copying or editing. Leave the password field empty and we remove those limits.
- We cannot recover a forgotten open password.
- Only unlock documents that you own or have permission to change.
Your files stay private
Your PDF and password are sent over a secure connection, used only to unlock the file, and deleted from the conversion service right after the download. We do not keep or share your documents or passwords.
Unlock PDF is free, works on phones, tablets and computers, and needs no registration.
