A little guidance. A better result.
How to use PDF Compare
Side-by-side pages, visual pixel difference and text diff — where practical for the files.
Prepare your input
Choose the original and revised PDFs.
Use the workspace
Inspect side-by-side pages, visual differences and the available text comparison.
Check your result
Check that the same pages are aligned before interpreting highlights.
Know the limits
Pixel changes can come from rendering or layout. Scanned pages have no text layer unless OCR already exists.
