FAQ

What types of differences does it detect?▾
The tool highlights visual differences between pages — changes in text, images, layout, and positioning are all detected through pixel-level and text-layer comparison.
Can I compare PDFs with different page counts?▾
Yes. The tool compares pages in order. If one PDF has more pages than the other, the extra pages are shown without a comparison counterpart.
Is the comparison done in my browser?▾
Yes. Both PDFs are loaded and compared entirely in your browser. Neither file is sent to a server.
Can I compare scanned PDFs?▾
Yes. The visual comparison works on any PDF, including scanned documents. It compares the rendered appearance of each page.
Can I export the comparison results?▾
You can take screenshots of the highlighted differences. A dedicated export feature for comparison reports is on the roadmap.
