A PDF Document Security password is a password used to set certain document restrictions (more on those below) in PDF files. The primary purpose of locking a PDF is to prevent access to unauthorized personnel.
Document restrictions put in place with an owner password can include the following:
Changing the document
Content copying for accessibility
Page and graphics extraction
Filling of form fields
Creation of template pages
If any password was applied to the PDF file by the owner of the PDF, then the password is required to open the PDF file and there is no workaround to remove the password from the PDF and open it if you don't remember the password.
But what if you:
Don’t know the password and it’s important you open the file.
Forgot the PDF password and you need to open the file.
A colleague didn’t send the password and you need to open the file now, not hours after they remember to reply.
