About Compare PDF Pages
Spotting what changed between two versions of a document is tedious when you do it by eye. A revised contract, an updated proposal, or a corrected report can hide small but important differences that are easy to miss flipping back and forth.
This tool compares two PDFs side by side so you can see where they differ. You upload both files and it lays them out for a clear comparison, helping you catch edits, additions, and removals quickly. It is free, runs in your browser without an account, and only reads your files to show the differences. It is a fast way to verify changes before you approve or sign anything.
