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.
