Compare Two PDF Files
Upload two PDF files and get a visual diff showing exactly what changed between them. Additions, deletions, and modifications are highlighted by page.
PDFRealm's compare tool performs a page-by-page visual comparison and highlights regions where the two documents differ. Useful for reviewing contract revisions, checking edited documents against originals, and auditing document changes.
The output is a diff report PDF that marks the changed regions on each page. For redacting sensitive content before sharing, see Redact PDF.
