About JSON Minifier
Compact JSON-like input
The minifier uses jsonminify to strip comments and unnecessary whitespace from JSON-like text. This makes it useful for cleaning configuration snippets or sample payloads that include comments before they are sent to stricter JSON consumers.
Pair with the formatter when reviewing
Use the formatter when you need to inspect structure, then minify the final payload when size matters. The related JSON Formatter is linked from this tool so you can move between readable and compact forms quickly.
