Compare PDF
See what changed between two versions of a PDF.
Your files never leave your device: everything happens in your browser.
How to Compare PDF
- Choose your file, or drop it on the box.
- Choose the old version, then the new one.
- Press Start, then download the result.
Compare PDF puts two versions of a document side by side. It lists the words added and removed on every page, and marks in red the places where the pages look different, so pictures and layout changes show up too. Download the result as a PDF report. Both files stay on your device.
