Minify JSON for production
Strip whitespace and line breaks to shrink JSON for network transfer or storage. Distinct intent from formatting—do not merge minify and prettify into confusing UI without labeling.

Frequently Asked Questions
- Minifier vs formatter?
- Minifier reduces size. Formatter increases readability. Use minifier before caching responses or embedding large configs; use formatter when debugging.
- Will minification change values?
- It should only remove insignificant whitespace. If numbers or strings change, you are not using JSON minification—double-check the tool options.
