Removed text is struck through and added text is highlighted. Only the text is compared, not fonts, colors or pictures: use Visual differences for those. Scanned pages have no text to compare.

How to compare two PDFs
- Choose the original PDF and the changed PDF.
- Read the text changes: removed words are struck through, added words highlighted.
- Switch to Visual differences to see pages where layout, pictures or formatting changed.
Two ways to compare
| Finds | Misses | |
|---|---|---|
| Text changes | Added, removed and changed words, across the whole document, even when text moved to another page | Changes in fonts, colors, pictures and layout |
| Visual differences | Anything that looks different on a page, marked in red | Changes that move everything after them (the rest of the page looks different too) |
Good to know
- "Find all pages that look different" checks every page and lists the ones that changed, with how much.
- Scanned PDFs have no text to compare; Visual differences still works for them.
- Tiny differences from different PDF programs (anti-aliasing) are ignored; move the slider to ignore more or less.

よくある質問
Can it compare a Word document with a PDF?
Save the Word document as a PDF first (File › Save As › PDF in Word), then compare the two PDFs.
Are my documents uploaded?
No. Both PDFs are read and compared in your browser, which matters for contracts and other confidential documents.
