1. What is PDF security?

PDF security is added to protect PDF files from viewing,editing, copying and so on.

Security Type: You can use either password to restrict users from opening, printing and editing PDFs,or use a certificate to encrypt PDFs so that only an approved list of users can open them.

2. Why we need to remove security from PDF?

Often we receive e-bills (on utility, telephone, Internet, mobile, cable and so on) in PDF format, and in consideration of the security, these PDF files have been protected with PDF password. PDFs which are protected cannot be changed, which means it is impossible to add links, bookmarks or combine pages from these files as part of your regular document operations. And it is extremely annoying for PDF users being locked out from the files when they have to get full access to these password-protected documents for personal or commercial use.

So, that's no wonder we often ask "Is there a tool available that can remove security from PDF files?", the answer is "Yes".

Remove security from PDF, also be known as removing password from protected PDF, unlocking PDF files, or recovering PDF files, allows PDF users to bypass the PDF security restrictions that were placed on the document by its creator, and finally allow users to 100% edit, print, copy, add context…
