Paste any XML document and get a compact, whitespace-free version ready for network transport, embedding, or storage. The minifier parses the input with DOMParser and re-emits it without indentation.
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
- Is my XML data sent anywhere during minification?
- All minification runs in your browser using native DOM APIs. Our servers are not involved at any point.
- 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.
- 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.
