À propos de JSON Minifier

This JSON minifier removes all unnecessary whitespace, line breaks, and indentation from your JSON to produce the smallest possible output. Paste formatted or pretty-printed JSON and get a compact single-line result. Optionally sort object keys alphabetically for consistent output. The tool shows original and minified sizes so you can see exactly how many bytes were saved. Use it to reduce payload sizes for APIs, configuration files, or localStorage data.

Questions fréquentes

What does JSON minification remove?
Minification removes all whitespace between JSON tokens — spaces, tabs, newlines, and indentation. The result is valid JSON with the smallest possible character count. No data is lost.
How much space does JSON minification save?
Savings depend on how much whitespace the original has. Pretty-printed JSON with 2-space indentation typically shrinks by 30–50%. The tool shows exact byte counts for both sizes.
What does sorting keys do?
When enabled, all object keys are sorted alphabetically at every nesting level. This produces deterministic output — useful for comparing JSON documents, generating consistent hashes, or storing in version control.
