Frequently asked questions

Can Compare PDF detect layout changes?

The comparison can identify page-level and text-level differences. Visual shifts, font substitutions, or complex graphics may require human review of the rendered pages.

Do both PDFs need the same page count?

No. Added, removed, or reordered pages are useful comparison results and are reported as structural differences.

Can I compare scanned documents?

Scans need OCR for meaningful text comparison. Without a text layer, the workflow can still compare rendered page appearances where supported.
