CONVERTERS

XML Formatter & Minifier

Format XML for readability or remove whitespace for compact output.

MARKUP FORMATTING

Format XML locally

Browser-only
Runs entirely in your browser. This is a formatter, not an XML validator.

XML text is formatted locally and is not sent to a server.

XML formatter and minifier guide

Format XML for readability or compact it for transmission. The markup stays in your browser.

Use the output to inspect structure, but validate against the application’s schema and parser when correctness matters.

Readable XML structure

Indentation makes nested elements, attributes, namespaces, and repeated records easier to inspect. Minification removes whitespace between tags but does not redesign the document.

Formatting versus validation

This tool does not validate against a DTD, XSD, namespace contract, or application schema. It also does not repair malformed XML.

Preserve meaningful content

  • Review mixed content, CDATA, comments, processing instructions, and whitespace-sensitive text.
  • Keep namespaces and attribute values intact.
  • Test the result with the same XML parser used by your application.
Tip: Keep the original document: whitespace can be data for some XML consumers, especially in mixed-content documents.

Frequently asked questions

Does this validate XML?

No. It formats or minifies XML but does not validate it against a schema.

Can I use XML comments?

Yes, but remember that minification and downstream tooling may treat comments differently.

Does minification remove element content?

It removes whitespace between tags. Review mixed-content documents because whitespace can be meaningful.

Privacy note: XML formatting happens in your browser. Your markup is not stored or uploaded.
