JSON minifier
Minify JSON, free.
Drop a .json or .txt file, pick how hard to squeeze, and download a compact version. The byte saving is measured on your file, and the output stays valid JSON.
Common questions
- What does minifying JSON actually do?
- It removes the spaces, indentation, and line breaks that make JSON readable but add bytes. The data stays identical; only the formatting is stripped.
- Is the minified JSON still valid?
- Yes. The output parses to exactly the same value as your input, just without the extra whitespace, so it drops straight into any JSON parser.
- Which preset should I use?
- Chill does a light pass, Medium is the balanced default, and Aggressive squeezes the hardest. Try one, check the measured saving, and switch if you want more.
