Compare text or JSON with syntax-aware highlighting. JSON is automatically formatted and normalized for easier reading.
The Diff Tool helps you instantly compare two text inputs and visually highlight differences. Whether you’re reviewing code changes, editing articles, or checking JSON responses, this tool makes it effortless to spot additions, deletions, and modifications.
It’s entirely browser-based — no uploads, no servers, no privacy risks. Paste your old and new text, and see what changed in milliseconds with color-coded highlights.
Useful for developers, writers, and QA testers who need a clean, fast, and private way to compare text, JSON, or code blocks without relying on external tools or IDEs.
