Basic example

Input XML

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <item id="1">
    <name>Product</name>
    <price>29.99</price>
  </item>
  <item id="2">
    <name>Service</name>
    <price>49.99</price>
  </item>
</root>

Minified XML

<?xml version="1.0" encoding="UTF-8"?><root><item id="1"><name>Product</name><price>29.99</price></item><item id="2"><name>Service</name><price>49.99</price></item></root>

Minification options

Comparison with/without option:

Original code

  <!-- This is a comment -->
  <item>Content</item>

    <item>   Multiple   spaces   </item>
    <data>  Text  </data>
</root>

With collapseWhitespace: true

<root><item> Multiple spaces </item><data> Text </data></root>

With collapseWhitespace: false

<root><item>   Multiple   spaces   </item><data>  Text  </data></root>

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.
