A visual diff compares and shows differences between rendered (or displayed) documents, as opposed to showing the text (or markup) that is used to format such documents.

Since 2017, the main approach for visual diffs in MediaWiki is the visual diffs system (pictured) provided by the VisualEditor extension, which compares the HTML of two documents. It provides visual diffs in VisualEditor's editing preview, as well as (still as a beta feature) in MediaWiki's standard diff display.
