도구 소개

Strip every bit of whitespace from your JSON to produce the smallest valid payload. Useful before embedding JSON in URLs, cookies, or config blobs where every byte counts.

도구 개요

Minified JSON is the same value expressed without newlines or indentation. This tool round-trips your input through the strict JSON parser — which catches trailing commas, comments, and unquoted keys — then re-serializes with no whitespace. Byte counts before and after are displayed so you can see the savings at a glance. All processing is client-side.

  • Handle developer workflows directly in the browser with no install required.

자주 묻는 질문

Does minification change meaning?+
No. The parsed value is identical; only formatting is removed.
Why does it say "Unexpected token" or similar?+
The input is not strict JSON. Trailing commas, single quotes, comments, or unquoted keys are not allowed by the JSON spec.
Does it sort keys?+
No. Key order is preserved. If you need deterministic sorting, handle that upstream.
