Häufig gestellte Fragen
Is this PDF compare tool free?
Yes, completely free with no usage limits.
How does the comparison work?
We extract the text of each PDF with PDF.js and compute a word-level diff. Added text is highlighted green, removed in red.
Does it work with scanned PDFs?
No — scanned PDFs have no embedded text. Run OCR on both first, then compare the .txt outputs separately.
Will my PDFs be uploaded to a server?
No. Both files are read and diffed in your browser. Nothing leaves your device.
What format is the output?
A self-contained HTML report you can open in any browser, including in dark mode.
