Guide

Why compare PDFs

Comparing PDFs is either pixel diff or text stream diff — and they answer different questions. Pixel diff catches moved logos; text diff catches changed clause numbers even when layout shifts.

  • Visual highlights

    Changes stand out without manually scrolling two monitors.

FAQ

compare PDFs — frequently asked questions

Text or pixel diff?

Visual comparison highlights rendering differences — best for layout-sensitive docs.

Scanned PDFs?

OCR first for text-centric diff elsewhere; visual diff still catches scan artifacts.

Password PDFs?

Unlock first.

Free?

Yes.

File size limits?

Large files take longer to render both sides.

How does visual diff differ from enterprise CLM tools?

Enterprise contract lifecycle platforms offer clause scoring and routing. DSNOOPDOC offers fast visual diff for everyday document review.
