What does JSON minification do?

Minification removes all unnecessary whitespace, indentation, and line breaks from JSON while preserving the data. This typically reduces file size by 20-50%, resulting in faster network transfers and lower bandwidth usage.

Can minified JSON be read by machines?

Yes. Minified JSON is fully valid and parseable by all JSON parsers. Only the formatting is removed — the data structure and values remain identical.

FAQ

Only whitespace (spaces, tabs, newlines) is removed. All keys, values, and structure remain unchanged. The result is valid JSON that any parser can read, but smaller in file size for faster transfers.
