JSON Minify
Minify JSON data by removing whitespace and formatting
Sample Data
Minification Tips
- • Minification removes all unnecessary whitespace and formatting
- • The JSON structure and data remain completely unchanged
- • Use minified JSON in production for faster loading times
- • Keep formatted JSON for development and debugging
- • Combine with gzip compression for maximum size reduction
Paste your JSON, click Minify, get a single compact line
Drop any valid JSON into the input area — formatted, nested, or already partially stripped. The tool calls JSON.parse then JSON.stringify in sequence, which removes all whitespace, newlines, and indentation while guaranteeing the output is still valid JSON. The stats strip immediately below the output shows original size, minified size, bytes saved, and the compression percentage so you know exactly how much weight you cut.
When to use the Export Report button
If you're logging file-size changes across a build process or need to show a before-and-after to a teammate, hit Export Report. It downloads a text file with both the original and minified output alongside the compression figures. The three sample buttons — Simple Object, Nested Object, Array Data — load pre-built JSON so you can see a representative result before pasting your own data. Everything runs client-side; nothing leaves your browser.
