Removed PDF Password But Document Still Asks for Password
A PDF where you removed the password but the file still prompts for a password on opening has either two separate passwords (open + permissions), or the save did not actually write the unencrypted version. Here's how to fully remove PDF encryption.
Removing a password from a PDF and finding the file still prompts for a password when opened is almost always caused by two separate issues: either the PDF has both an open password and a permissions password (and only one was removed), or the unlocked version was not saved correctly — the tool showed a success message but you still have the original encrypted file.
Two Types of PDF Passwords
PDFs can have two separate passwords: (1) Open password (User password): required to open and view the document. Entering the wrong password shows the document. (2) Permissions password (Owner password): controls what operations are permitted — printing, copying, editing. Some tools only remove the open password, leaving the permissions password intact. The file then opens without a password prompt, but features are restricted. To fully decrypt the PDF, both passwords must be removed.
Verify the Saved File Is Actually Unlocked
When an online tool or Acrobat reports "password removed," the unlocked version is the downloaded file — not the original. If you opened the original file in Acrobat, entered the password, and then saved as a new PDF, the new file should be unlocked. But if the tool showed a success notification while you were still viewing the original, check which file you are opening. In Acrobat: File → Properties → Security tab — "Security Method" should show "No Security" after successful password removal.
Using FixMyPDF to Remove All Encryption
Use FixMyPDF Unlock — enter the current password (either the open password or the owner password, whichever you know), and it removes all encryption from the PDF. The downloaded file has no password at all. If you know only one of the two passwords, entering the owner password is sufficient to unlock all restrictions including the open password requirement. After downloading, open the file fresh — it should open immediately without any password prompt.
Cannot Remove Password Without Knowing It
If you have a PDF you cannot open (forgot the open password), password removal requires knowing the password. There is no legitimate online tool that can bypass an AES-256 encrypted PDF without the password. Short passwords (under 6 characters) can sometimes be recovered by brute-force search tools for PDFs created with older RC4 encryption. For modern AES-128/256 encrypted PDFs with strong passwords, recovery is not feasible. The practical solution: contact the sender for the password, or if the PDF is a document you created, check password manager apps, email history, or documents where you noted the password.
