Frequently Asked Questions

Why do my two PDFs show as identical when they look different?

Compare uses extractable text only. Scanned pages or image-only PDFs may have no text layer—run OCR PDF first, or use PDF to Text on each file to verify extraction.

Is this a legal document comparison?

No. This is a technical text diff for convenience. It is not legal advice and may miss layout, images, or metadata differences.

Are my files stored?

Files are processed temporarily and deleted per the site retention policy (typically within one hour).

Files are automatically deleted after one hour for privacy.
