Words, not layout. This compares the words of both files, not their layout, pictures or fonts. A scanned PDF has no words to compare: make it searchable first.
Why isn't this free? Reading two whole documents and writing a report takes real work on your device. The summary and the first change are always free.

Questions about this tool
Are my files really not uploaded?
Yes. Your browser does all the work on your device. You can check it yourself: turn off your Wi-Fi after the page has loaded and the tool keeps working.
The tool says my file is too big.
Phones and older computers have less memory. Open the page on a computer, or choose a lighter option such as cutting a shorter part first.
Is it really free?
Yes. During the beta every tool is free, downloads included, with no account. Paid plans will be announced on this site first, and nothing you make during the beta is ever charged.
What counts as one action?
One result is one action. Combining several PDFs into one file is one action. You can retry or download the same result again for 24 hours.
