Beautify XML Online — Free XML Beautifier
Beautify XML documents instantly with consistent indentation. All processing stays in your browser.
Features
Format XML documents with consistent indentation while preserving CDATA sections and processing instructions.
Format XML documents with consistent indentation while preserving CDATA sections and processing instructions.
Basic example
Minified XML
Beautified XML
Minification options
Indentation size
Number of spaces (or tab width) used when formatting XML.
Indent type
Use spaces or tabs for indentation when beautifying XML.
XML conversion helpers now have dedicated URLs
Use standalone flows for interoperability: jump to XML → JSON, XML → YAML or XML → CSV while keeping XML minification and beautification centered on FastMinify’s primary XML formatter.
XML Formatting and Beautification
Proper XML formatting makes documents easier to read, debug and maintain. Our formatter adds consistent indentation, aligns attributes, and organizes elements hierarchically. This is especially useful for configuration files (web.xml, pom.xml), SOAP responses, and XML data feeds.
Minifying XML Sitemaps
XML sitemaps can grow large for sites with thousands of pages. Minifying your sitemap.xml removes unnecessary whitespace and comments, reducing file size and improving crawl efficiency. Our tool handles sitemap-specific elements like loc, lastmod, changefreq and priority correctly.
Frequently Asked Questions — Beautify
Everything about beautification
What does the XML beautifier do?
It formats XML with consistent indentation while preserving CDATA sections and processing instructions.
Convert to JSON, YAML or CSV?
Use dedicated converters (XML → JSON, XML → YAML, XML → CSV) from the Convert menu.
Beautify vs minify?
Beautify for readability; minify XML to shrink file size.
Is my XML uploaded to a server?
No. Beautification runs entirely in your browser — your XML never leaves your device and is not stored by FastMinify.
Beautify vs unminify — which should I use?
Beautify formats readable XML; unminify restores compressed output — try the XML unminifier. For day-to-day formatting, stay on XML beautifier.
Can I customize indentation?
Yes — pick 2 or 4 spaces or tabs in the Beautify options toolbar.
