02 / QUESTIONS
Good to know.
Does it compare scanned pages?+
Text comparison needs a text layer. Scanned pages need OCR first.
Can I compare more than two files?+
Compare works in pairs.
Does it show formatting changes?+
The focus is content differences; visual styling changes may not be highlighted.
