FAQ
Does it compare scanned PDFs?
No. Run OCR first and verify that the PDF contains selectable text.
Does a matching result prove the PDFs are identical?
No. It means the extracted text agrees; images and formatting may still differ.
Are my PDFs uploaded?
No. PDF parsing and comparison happen locally in the browser.
