## About

Compare Diff Online is a free browser-based comparison tool for developers, editors, writers, and reviewers. It compares text, source code, JSON, and documents with clear line, word, and character views. Files and text are processed locally in the browser, so users can inspect changes without uploading private content or creating an account. It is useful for code reviews, document revisions, configuration checks, and quick side-by-side comparisons.
