How to Use the XML Minifier

Paste your formatted or pretty-printed XML into the input field.

The tool removes all non-significant whitespace — indentation, line breaks, and spacing between tags.

Copy the minified XML for production use, transmission, or storage.

What Is XML Minification?

XML minification removes whitespace characters that exist only for human readability — indentation, newlines between elements, and spaces between attributes. The resulting document is functionally identical to the original but smaller in size. For XML documents transmitted over the network or stored at scale, minification reduces payload size and can improve parse performance. The trade-off is that minified XML is not intended to be read or hand-edited — use the XML formatter to restore readable indentation when needed.

When to Use This Tool

Reducing SOAP payload size — Minify XML request and response bodies to reduce bandwidth in high-volume API traffic.

Optimizing XML config files for deployment — Strip formatting from XML configs that ship with production builds.

Preparing XML for storage — Minified XML takes less space in databases or blob storage when stored at volume.

Benchmarking XML parsers — Use consistent minified XML as input when measuring parser performance.
