ComparePDF is used to compare PDF files—textually or visually.


ComparePDF for Windows is an application for comparing PDF files.
(If you require a console–command line–tool, use our comparepdfcmd application instead.)

Application: ComparePDF
The trial license key will be specific to this machine. (Download and install ComparePDF if you haven't already done so. Then run the program. It should automatically acquire a free trial license key (unless you've already had one). But if this fails, then copy the Computer ID from ComparePDF and paste it here.

Note that only one trial per application per major version per machine is allowed.
Trial license keys are valid for 20 days.
