Compare two PDF files

Open two versions side by side, find changed pages, and inspect the highlighted differences in each PDF.

We count which tools are used most, without including entered values or file contents in the statistics. Privacy

How it works and what to check

Upload the original and revised PDFs, then run the comparison. In the panel below the files, select a count to filter the pages and use the menu or arrows to move between pairs. On a phone, you can switch between versions. At higher zoom, switching keeps your place as far as the other page allows. Zoom in for details: red highlights on the revised PDF mark visual differences. On desktop, the two previews scroll together when the page is present in both files.

Compare two versions where a cover was added and a price changed. Visually identical pages anchor the alignment. A moved page may appear as removed and added.
