XML Formatter is a free online tool to format, indent and tidy XML. It runs entirely in your browser, so your files never leave your device — nothing is uploaded. There's no sign-up, no watermark, and it works on any modern browser on desktop or mobile.
How to use XML Formatter
This free XML formatter beautifies XML with proper nesting and indentation, or minifies it down for compact storage. It is handy for config files, RSS and Atom feeds, SVG markup and API responses that arrive as a single dense line. Formatting runs entirely in your browser, so your XML documents stay private on your device.

Clear nesting
Elements are indented by depth so deeply nested structures become easy to read.
Versatile
Works with config files, feeds, SVG and API payloads alike.
Private by default
XML is formatted client-side, so sensitive configuration and data never leave your browser.
XML Formatter — frequently asked questions
Can it format SVG files?
Yes. SVG is XML under the hood, so the formatter indents and tidies SVG markup just like any other XML document.
Does formatting validate my XML?
Formatting reflows well-formed XML and will surface obvious structural problems, but it is primarily a beautifier rather than a full schema validator.
Is my XML uploaded anywhere?
No. The tool processes everything locally in your browser, so your config files and API responses are never transmitted to a server.
