Minify XML

Paste any XML document and get a compact version, with the whitespace between elements removed, ready for network transport, embedding, or storage. The minifier parses the input with DOMParser and re-emits it without indentation.

Runs entirely in your browser

How it works

The tool uses the browser's native DOMParser to build an in-memory tree from your XML, then walks the tree to emit either an indented or minified result. Validation reports the parser's error message when a document cannot be parsed.

Processing runs in your browser

All parsing and formatting happens locally in your browser tab. Our servers are not involved at any point.

Frequently asked questions

Does minifying remove comments?
Comments, processing instructions and CDATA sections are kept in the output. The minifier removes only the whitespace between elements, so a comment that documents a setting is still there after minifying. Delete comments by hand first if you need the smallest possible file.
Is whitespace inside text changed?
Whitespace inside text is kept, including the spaces in <name> Ada </name>, and mixed content such as <p>Hello <b>world</b></p> is left untouched. Only whitespace-only text between child elements is removed, along with the line break after the XML declaration.
Why minify XML?
Minified XML payloads are smaller, which reduces bandwidth on the wire and storage cost when XML is embedded in databases, message queues, or static assets.
Does minification change the document's meaning?
Minification only removes inter-element whitespace. Element names, attributes, text content, CDATA blocks, and the overall structure remain identical. Entities declared inside the DOCTYPE are written out as their expanded text.
Can minified XML be parsed by other tools?
Yes. Minified XML is fully valid and parses correctly in every standard XML library.
Will the minifier reject invalid XML?
Yes. If DOMParser reports a parser error, the tool surfaces it instead of producing a result.
