JSON Minifier

Minify JSON to its smallest form.

Paste JSON to remove all whitespace and produce the smallest valid JSON. Invalid JSON is reported so you can fix it first. Everything runs locally in your browser.

Your input is processed locally in your browser — nothing is uploaded, stored or logged.
