Hi Sarah.
There are many ways to unlock a PDF file such as online utility, adobe acrobat pro, or using a third party tool. As you are asking for the trusted Software, so you can go with a PDF Protect and Unprotect Tool from SysInfotools which lets the users apply password protection (user as well owner) and other security parameters to protect PDF files. This smart multi-functional tool enables users to secure PDF files with password-protection and other types of securities. You can easily unlock the PDF file in one go with this utility.
