Frequently asked questions

Does this compare formatting or just text?

This compares the extracted text content of each page, not visual layout or formatting.

What if a PDF is a scanned image?

Text-based comparison requires selectable text; scanned PDFs need OCR first.

Is this private?

Yes, both files are processed entirely in your browser.
