Frequently Asked Questions

Why use visual comparison instead of text comparison?

Office PDFs often change layout, signatures, stamps, images, or scanned pages. A rendered-page comparison catches what a recipient actually sees.

Can this find tiny changes?

Use High sensitivity and Detailed render scale for smaller visual edits. Very large files may take longer because every page is rendered in the browser.

Does this replace legal document review?

No. It is a browser-local visual review aid. Use formal review tools when you need legal-grade change tracking or text provenance.
