XML Minifier
Note: Minification removes all unnecessary whitespace to reduce file size. The XML remains valid and functional. Use our XML Formatter if you need to beautify XML instead.
About XML Minifier
XML minification reduces file size by removing all unnecessary whitespace and line breaks from XML documents. This is essential for production environments where bandwidth and file size matter. Minified XML reduces network transfer times and improves application performance. The tool validates XML syntax before minifying to ensure the output is well-formed. All minification happens entirely in your browser—your data is never sent to any server, ensuring complete privacy and security.
How to Use
- Paste or type your XML into the input field.
- The tool will automatically minify and validate your XML after a brief pause.
- Click "Minify" to manually trigger minification.
- View the size reduction statistics showing original size, minified size, and savings.
- Click "Copy" to copy the minified XML to your clipboard.
- Use the minified XML in your production applications or data transfers.
Frequently Asked Questions
What is XML minification?
XML minification is the process of removing all unnecessary whitespace, line breaks, and indentation from XML documents without changing the structure or content. This reduces file size while maintaining validity, making it ideal for production environments where bandwidth and performance matter.
When should I minify XML?
Minify XML when you need to reduce file size for production deployments, API responses, data transfers, or configuration files. Minified XML reduces bandwidth usage and improves load times. Keep formatted XML for development and debugging where readability is important.
Will minification change my XML data?
No! Minification only removes unnecessary whitespace between tags. The XML structure, elements, attributes, and content remain completely unchanged. The minified XML is still valid and can be parsed normally by any XML parser. Whitespace within text content is preserved where significant.
Does minification validate XML?
Yes! The minifier validates XML syntax before minifying using the browser's DOMParser. If your XML is invalid (unclosed tags, improper nesting, etc.), you'll see a detailed error message. Only valid, well-formed XML can be minified.
How much size reduction can I expect?
Size reduction depends on how much whitespace and indentation your original XML contains. Well-formatted XML with indentation typically sees 20-50% reduction. The statistics panel shows exact savings for your specific XML.
Can I undo minification?
Yes! Use our XML Formatter tool to beautify minified XML. The formatter adds proper indentation and line breaks to make XML human-readable again. Both tools work together—format for development, minify for production.
Are XML namespaces preserved?
Yes! XML namespaces, namespace prefixes, and xmlns declarations are fully preserved during minification. The minified XML maintains all namespace information and remains functionally identical to the original.
What about CDATA sections and comments?
CDATA sections (<![CDATA[...]]>) are preserved during minification. Comments (<!-- ... -->) may be removed or preserved depending on the browser's XML serializer. If you need to keep comments, verify the output.
Is my XML data secure?
Absolutely! All XML minification happens entirely in your browser. Your data is never sent to any server, ensuring complete privacy and security. This tool works offline once loaded.
