Compare PDF
Side-by-side text and visual diff between two PDF revisions.
See what changed between two PDFs.
Compare PDF lines up two versions of a document page by page — including pages that were added, removed, or reordered — and shows you both what changed: a text diff (added, removed, and edited paragraphs) and a visual diff (a pixel-level overlay highlighting where the page image itself changed). Page matching is best-effort: pages are aligned by their extracted content, which works well for typical edits but can be thrown off by documents with many near-identical or blank pages.
