About Compare PDF

Compare PDF shows two documents side by side with synced previews and per-page text-difference highlighting. Reviewers searching "compare PDF", "PDF difference checker", or "compare two PDFs" need a faster way to spot wording changes between versions.

Upload both PDFs and inspect differences page by page. Text comparison works best on text-based PDFs; pure image scans may show limited textual diffs.

Visual layout shifts can still matter even when text matches. Use human judgment for legal redlines - automated compare is a helper, not a law-firm redline system.
