About this tool
Compare the text layer of two PDFs, page by page.
This is not a visual overlay. Images, stamps, and position changes are ignored. Lines that match are unmarked; lines only in the first file start with a minus, and lines only in the second start with a plus.
Long pages are trimmed so the browser stays responsive. Scanned PDFs with no text layer look empty.
Quick steps
- Choose file A and file B.
- Run the comparison.
- Read the page sections that differ.
Both files stay in your browser.
FAQ
Why can two files look different but show no text changes?
A moved image or a font change does not alter the extracted words. Use PDF to Images if you need to look at pixels.
