Frequently asked questions

What does it compare?

The text of both documents, word by word. Design changes (colors, images) aren't detected.

How do I see the changes?

In the list of differences and in a PDF with the pages side by side: in red what was removed from the original and in green what's new.

Does it work with scanned PDFs?

Only if they have text. If they are photos, run them through “Image to text” first and then compare them.

Are my files uploaded?

No. The comparison is done on your device.
