What is XML Minification?

XML minification removes unnecessary whitespace — indentation, line breaks, and spaces between tags — to produce the smallest possible XML string that is still syntactically valid. Minified XML is commonly used in SOAP API requests, XML-based message queues, Android resource files compiled for deployment, and any situation where payload size matters. This tool also removes XML comments (which are never required for processing) and collapses empty elements to self-closing form (<tag/>). Everything runs entirely in your browser.

  • Strips all whitespace-only text nodes between elements
  • Removes XML comments (not needed for processing)
  • Collapses empty elements to self-closing form
  • Shows exact byte savings and compression percentage
  • To restore readability, use the XML Formatter

Frequently Asked Questions

Does minified XML still work in parsers?

Yes. Whitespace between elements is not significant in XML (unless preserved with xml:space="preserve"). Any standards-compliant XML parser will process minified XML identically to formatted XML.

Are XML comments removed?

Yes. XML comments are stripped during minification since they serve no processing purpose and add size. If you need to preserve comments, use the formatter instead.

Is my data safe?

Yes. All processing happens entirely in your browser. No data is sent to any server.
