Format or minify XML safely in your browser. Free, private, runs in your browser.
100% private — your files and text never leave your browser. All processing happens locally on your device.
XML Formatter validates and formats XML in the browser, preserving source constructs such as namespaces, comments, CDATA, processing instructions, and attributes where practical.
The formatter does not resolve external entities, fetch doctypes, or retrieve remote resources. External references are treated as source text and surfaced as warnings instead of network activity.
Use formatted output for review and minified output for compact files. Invalid XML produces a local error with line and column information when the parser can provide it.

Yes. The formatter keeps namespace prefixes and attributes in the source output.
