    Frequently asked questions

    Is it free?

    Yes. Comparing is free, needs no account and has no limits.

    Are my files uploaded?

    No. Both PDFs are compared in your browser, which matters for contracts and private documents.

    What does it compare?

    It compares the words. Changes in pictures, colours or layout are not shown.

    Can I compare scanned PDFs?

    Scans are pictures, so they have no words to compare. Make both files searchable with OCR PDF first.

    What is in the report?
