Legal and procurement teams receive revised contracts where redlines are missing or untrustworthy. Side-by-side pixel or text-aware comparison surfaces added commas, deleted indemnity clauses, and swapped exhibits faster than manual line reading.

Siliph Compare PDF aligns pages in the browser-backed engine with encrypted uploads, marking additions in one color and deletions in another. Scanned comparisons work when OCR layers exist; purely image scans compare visually.

Use comparison output as an internal QA step before signing—export a summary PDF for audit trails showing exactly what changed between draft v3 and v4. Large documents may compare faster when you extract changed chapters first with Extract Pages.

Auto-deletion within two hours on the free tier protects negotiation confidentiality, and comparison requires no signup. Flatten PDF afterward if the comparison report itself must be immutable.

Pair with Redact PDF when differences reveal confidential third-party names that should not appear in the shared comparison file.

Siliph edit utilities—crop, rotate, headers, Bates numbers, metadata—apply changes in the browser with encrypted handling from the moment you drop a file. Finished PDFs auto-delete within two hours on the free plan, and every edit workflow opens without signup.
