Minify JSON
Strip whitespace from JSON to make it as small as possible.
What to know
Minifying removes every space and line break outside string values. The data is unchanged; only the formatting goes.
Key order is preserved exactly as written, since JSON objects retain insertion order in every current engine.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
