Key points
  • Know what it cannot do
  • Ask the sender
  • Look for another way

Remove a Password from a PDF only removes a password you already know. It does not guess or crack passwords.

What to do

  1. Ask the person who sent the PDF for the password again.
  2. Look in your email or notes.
  3. If it is still unknown, ask the creator to reissue the PDF.
