Minify Payloads

Generate compact JSON/XML output and copy or download instantly.

Minify JSON, XML, YAML & CSV in your browser

Compact your data for the wire. Paste JSON, XML, YAML, or CSV and the minifier removes insignificant whitespace and newlines to produce the smallest valid output — ideal for embedding in code, shrinking API request bodies, or cutting bandwidth. Auto-detect picks the format, or you can set it explicitly.

Processing is 100% client-side, so nothing you paste is uploaded or stored. It is free, needs no account, and works offline once the page has loaded. Copy the result or download it as a file with one click.

Does minifying change my data?

No. Only insignificant whitespace is removed — the parsed value is identical. The output round-trips back to the same structure.
