About Compare PDF
Compare PDF shows two versions of a document side by side, page by page, and highlights what changed: words removed from the first file in red and words added in the second file in green. Scanned PDFs are compared pixel by pixel instead.

More about Compare PDF
Everything runs in your browser, so contracts and agreements stay private, and you can download a comparison report as a PDF.
Tips
- Add the older version first and the newer version second — drag the files in the strip to swap them.
- Pages are compared in order (page 1 with page 1), so a page inserted in the middle shows up as many changes after it.
