About this tool
Unlock a PDF you already have access to by removing its password protection, so it opens instantly without prompting for a password. You'll need to enter the current password once, and everything is decrypted locally in your browser.
Limits and edge cases
- A correct password is required. A wrong one produces the message asking for the correct password, and there is no guessing or recovery feature.
- Only one file is handled at a time. Unlock several documents by repeating the steps.
- If the file opens without any password, the tool says so and still lets you run it to get a re-saved copy, which may not be byte-for-byte identical.
- A file that is not a valid PDF, or is damaged, fails with a general "Incorrect password, or the file is not a valid PDF" error, so the message cannot tell those cases apart.
- The downloaded copy is no longer protected. Anyone who gets it can open it, so store or send it accordingly.
If unlocking doesn't work: what to check
- "Please enter the correct password" The file is encrypted and the password did not match. Passwords are case sensitive, so check caps lock and any characters your keyboard layout may have changed. Copy-pasting from the original email often brings along a trailing space.
- "Incorrect password, or the file is not a valid PDF" A different failure that shares one message. Try opening the file in another PDF viewer. If it will not open there either, the download was probably cut short and needs to be fetched again. If it opens with the password but not here, it may be a variant the library cannot read.
- "No password was detected" Nothing asked for a password, so there was nothing to remove. If a merge or edit still fails on this file, the cause is elsewhere. Try Merge PDF or Split PDF directly on the original.
- You want protection back after editing The unlocked copy is plain. Once you have finished, add a new password with Protect PDF. For background on what happens to files in online tools, read does a PDF tool actually upload your file.

Frequently asked questions
Can this crack or bypass a password I don't know?+
No. The tool only opens a file with the password you type in, and it has no guessing or recovery feature. If you have forgotten the password, ask whoever created the file or sent it to you for a new copy.
Is my password or file uploaded anywhere?+
No. The file is read and decrypted by JavaScript running in your browser tab, and the password is used only there. You can check this yourself by watching the Network tab in developer tools while you unlock a file.
Will unlocking change the content of my PDF?+
The pages, text and images are copied into the new file as they are. What changes is that the file is saved again without encryption, so its internal structure and file size may differ slightly from the original.
Why does it say incorrect password or not a valid PDF?+
That message covers both a wrong password and a file the library cannot read as a PDF. Check the password for typos, capitalization and keyboard layout first, then confirm the file opens in another PDF viewer.
Can I unlock a PDF and then merge or split it?+
Yes. Merge and split cannot read an encrypted file, so unlock it first, then use the downloaded copy in those tools. If you want protection back afterwards, you can add a new password with Protect PDF.
What is the downloaded file called?+
The download keeps your original file name and adds "-unlocked" before .pdf. Your original stays untouched on your device, so you keep both the protected and unprotected versions.
