🔍 Compare PDFs

Generates a visual diff between two PDF documents. Upload the original and the revised version — each page is rendered as an image and compared side by side. Changed regions are highlighted: red for content only in the original, green for content only in the revised version. Configure the render DPI (72, 96, 150, or 300) and the detection sensitivity. A summary of all differing pages is included in the output. Processing uses PyMuPDF server-side.

Pages are rendered at 150 DPI and compared pixel-by-pixel. Changed regions are highlighted — red for content only in the original, green for content only in the revised version. A summary page lists all differing pages.
