FAQ

We extract text from each page using PDF.js, then compare the text content page by page using our diff engine.

Scanned PDFs that contain selectable text (OCR-processed) will work. Pure image-only scans need OCR processing first.

No hard limit. Performance depends on your browser and the complexity of the PDFs.
