What does JSON minification do?

JSON minification removes all unnecessary whitespace, newlines, and indentation from JSON data while preserving the data structure. This reduces file size and improves transfer speed.

How much size can I save?

Typical savings range from 30-50% depending on how much whitespace was in the original JSON. Well-formatted JSON with lots of indentation can see even higher savings.

Is minified JSON still valid?

Yes! Minified JSON is 100% valid JSON. JSON.parse() and all JSON parsers work exactly the same with minified data.

Should I minify JSON for APIs?

Yes! Minifying JSON responses from APIs reduces bandwidth usage and improves response times, especially for mobile users and large datasets.

Does this tool validate JSON?

Yes! Before minifying, we validate the JSON structure. If there are syntax errors, you'll see an error message instead of minified output.
