What is XML minification?

XML minification removes all non-significant whitespace — spaces, tabs, and line breaks between tags — to produce the smallest valid XML document. The content of text nodes is preserved; only inter-element whitespace is stripped.

Use minified XML for production SOAP requests, API payloads, configuration values stored in databases, and embedded XML strings. Minified XML can be 30–60% smaller than its prettified equivalent, reducing transfer time and storage cost.

How to minify XML

  2. The formatter is pre-set to minify (0 indentation). Click Format to compress.
  3. Copy the compact output with the Copy button or Ctrl+K.
