Indentation and comments make XML readable for humans but add extra bytes when transmitted over a network or stored at scale. This XML minifier strips out unnecessary whitespace, line breaks, and comments, producing the smallest valid version of your document while keeping tags, attributes, and content intact. It's commonly used before deploying config files, embedding XML in another format, or reducing the size of SOAP request payloads. The tool preserves meaningful whitespace inside text nodes and CDATA sections so content isn't accidentally altered. Since minification happens entirely in your browser, your XML is never uploaded to a server, and there's no signup needed. Paste your XML below to compress it instantly.

Frequently asked questions
What does XML minification remove?
It removes unnecessary whitespace, line breaks, indentation, and comments between tags, while preserving the actual element content and structure.
Does minifying XML change the data inside it?
No, minification only affects formatting characters - tag names, attributes, and text content remain exactly the same.
Why minify XML before sending it over a network?
Smaller XML payloads transfer faster and use less bandwidth, which matters for SOAP APIs, RSS feeds, and large configuration files.
Are XML comments removed during minification?
Yes, comments are stripped out by default since they're not needed for machine processing, though you can keep formatted originals as a backup.
Is my XML data uploaded when I minify it?
No, the entire process runs client-side in your browser, so your document never leaves your device.
Can I convert minified XML back to a readable format?
Yes, use the companion XML Formatter tool to beautify minified XML back into indented, readable markup.
Does minification affect CDATA sections?
No, content inside CDATA sections is preserved exactly as written since it may contain meaningful whitespace or markup-like text.
