What is the difference between minifying and formatting JSON?
Minify outputs the smallest single-line form; format adds indentation for readability. Neither changes the data values.
JSON Minifier
DevTools JSON Minifier compresses multi-line JSON into a single-line string by removing extra whitespace—ideal for API payloads and storage, processed locally in your browser.

About this tool
Minifying JSON reduces HTTP body size. The tool uses JSON.parse and JSON.stringify locally to ensure the output remains valid JSON.
How to use
- Paste the JSON to minify.
- Click Minify.
- Copy the single-line result.
FAQ
Can minified JSON still be parsed?
Yes. Minification only removes whitespace—JSON.parse works normally on the result.
Does it support Unicode characters?
Yes. The tool uses standard JSON.stringify, which handles Unicode correctly.
Is my JSON uploaded during minification?
No. Minification runs locally in your browser.
