Drop a password-protected PDF here
Nothing is uploaded. The PDF and your password stay in this tab.
A password you set months ago is protection; a password on a file you now need to print, merge or send onward is friction. This takes it off — provided you can still supply it.
Using Unlock PDF, step by step
- 01
Drop in the password-protected PDF.
- 02
Type the password that opens it.
- 03
Unlock, then download the PDF that opens without one.
What people use it for
- Take the password off a bank or payslip PDF before filing it with everything else.
- Remove protection from a document so it can be merged, split or compressed here.
- Open up an archived file whose password you still have but no longer want to type.
What goes in, and where it goes
- What it accepts
- One password-protected PDF at a time, plus the password that opens it. Every encryption revision in real use is covered — 40-bit and 128-bit RC4, AES-128 and AES-256. A PDF with no password is refused, because there is nothing to remove.
- What you get back
- One PDF that opens with no password in any reader. The pages, their order, their size, their content and the document's title and author are all unchanged — only the lock is gone.
- Where your file is processed
- Unlock PDF runs in your browser. The file and the password are both used only inside this tab: the password derives the decryption key and is then gone, and neither it nor the file is ever uploaded. Nothing is kept once you close the tab.
Common questions
Can this open a PDF if I don't know the password?
No, and it never will. The password you type is what decrypts the file — supply the wrong one and the document simply doesn't open. There is no recovery, cracking or guessing here, which is a deliberate choice rather than a missing feature.
What if the PDF opens fine but won't let me print or copy?
That file carries an owner password rather than an open password, and PDFBull will only remove it if you supply that owner password. Stripping a restriction for someone who can't authenticate against it is circumventing a control the author set, not unlocking a file you own.
Does anything about the document change?
Only the encryption. Pages, their order and sizes, the content, and the title and author are all preserved — the last of those takes deliberate work, because a decrypted document loses the pointer to its own metadata unless it is put back.
Is the password sent anywhere?
No. It is used in this tab to derive a decryption key and nothing else. It is never uploaded, never logged, never written into the downloaded file's name, and never included in an error message.
