What is KDiff3?

KDiff3 is a simple yet powerful tool for comparing different versions of text files or source code. It highlights differences between two or more files, making it easy to spot changes at a glance. Whether you are reviewing code edits, checking document revisions, or troubleshooting file discrepancies, KDiff3 provides a fast and visual “spot the difference” method.

In addition to comparison, KDiff3 also supports file merging, allowing users to combine multiple versions into a single document. While merging is a built-in feature, many users primarily rely on KDiff3 for its clear and efficient side-by-side comparison.
