JSON Minifier Tips

Minified JSON is semantically identical to the input - only whitespace is removed.
Tick "Allow comments" to minify JSONC / commented JSON from VS Code settings or tsconfig.
The size report shows bytes before and after, plus the percentage saved.
Paste the output into APIs, CI config, or anywhere byte size matters.

Vanlige spørsmal om Json Minifier-formatering besvart

Yes, completely free with no registration. All minification happens locally in your browser.

Minifying removes whitespace, line breaks and comments while keeping the data identical - no gzip is involved. Compressing usually means gzip or brotli, which the server applies afterwards.

Yes. Tick "Allow comments (JSONC)" and // as well as /* */ comments are stripped before parsing, including comments inside strings are preserved correctly.

No. JSON.stringify(JSON.parse(...)) produces the shortest standard representation of the exact same value. Number formatting follows JavaScript canonical output, e.g. 1.0 becomes 1.

It depends on how the input was formatted. Pretty-printed JSON with 4-space indentation typically shrinks 60-80%, while already-compact JSON stays almost the same size.
