How this page works

Use this page to compact JSON by removing unnecessary whitespace and line breaks. This is useful before embedding JSON into code, sending it through APIs, or reducing text size.

The tool parses the JSON before minifying it. That means broken JSON will be rejected instead of producing a misleading output.
