Frequently Asked Questions
How does the visual diff algorithm work?
Both PDF documents are rendered to canvas bitmaps at high resolution, and a pixel comparison highlights removals in red and additions in blue.
Can I compare documents with different page counts?
Yes. Pages that only exist in one document are flagged and visualized clearly.
Are my files uploaded anywhere?
No. The rendering and difference engine executes completely in your local browser.
Compare two PDF revisions side-by-side with automated pixel diffing. Spot changes, layout shifts, edits, and deletions instantly in your browser.
How it works
- Choose the two PDF versions to compare.
- Run the comparison. Both files are rendered and matched pixel by pixel.
- Review the highlighted changes: removals in red, additions in blue.
