What is document comparison?

Document comparison (also called document diff) spots the differences between two versions of a file. These differences might include changes in text, layout, or visual elements, making it easier for users to understand what has changed.

PDF comparison can be done visually by overlaying two PDFs to highlight layout differences, or by extracting and comparing text to identify content changes.
