How to Minify XML

1

Paste or upload XML

Enter your formatted XML in the input area or upload an XML file from your computer.

2

Click Minify

Press the Minify button to compress your XML by removing all unnecessary whitespace.

3

Review compression

See your minified XML and the compression statistics showing how much space was saved.

4

Copy or download

Copy the minified XML to clipboard or download it for use in your production environment.

XML Minification Example

See how minification compresses XML while preserving all data:

Before: Formatted XML

482 bytes
<?xml version="1.0" encoding="UTF-8"?>
<employees>
  <employee id="1">
    <name>John Doe</name>
    <department>Engineering</department>
    <email>john@example.com</email>
    <salary>75000</salary>
  </employee>
  <employee id="2">
    <name>Jane Smith</name>
    <department>Marketing</department>
    <email>jane@example.com</email>
    <salary>65000</salary>
  </employee>
</employees>

After: Minified XML

298 bytes (38% saved)
<?xml version="1.0" encoding="UTF-8"?><employees><employee id="1"><name>John Doe</name><department>Engineering</department><email>john@example.com</email><salary>75000</salary></employee><employee id="2"><name>Jane Smith</name><department>Marketing</department><email>jane@example.com</email><salary>65000</salary></employee></employees>

Benefits of XML Minification

Faster Network Transfer

Smaller file sizes mean faster upload and download times. For APIs handling thousands of requests, minified XML significantly reduces latency and improves user experience.

Reduced Bandwidth Costs

Less data transferred means lower bandwidth bills. For high-traffic applications exchanging XML, minification can result in substantial cost savings over time.

Faster Parsing

XML parsers process less data when whitespace is removed. While the difference per document is small, it adds up for applications parsing millions of XML documents.

Reduced Storage

Minified XML requires less disk space and database storage. For systems archiving large amounts of XML data, this can significantly reduce storage requirements.

Mobile Optimization

Mobile devices benefit most from minified XML due to slower network connections and limited data plans. Smaller payloads improve app responsiveness.

API Performance

SOAP and XML-based REST APIs serve responses faster with minified XML. Combined with compression (gzip), this creates optimal performance.

What Minification Removes (and Preserves)

Removed During Minification:

  • Indentation whitespace

    Spaces and tabs used for visual nesting

  • Line breaks between elements

    Newlines added for readability

  • Trailing whitespace

    Spaces at the end of lines

  • Multiple consecutive spaces

    Extra spaces between attributes

Preserved During Minification:

  • Text content

    All text between element tags

  • Significant whitespace

    Spaces within text content

  • CDATA sections

    Content inside CDATA is untouched

  • Attribute values

    All attribute content preserved exactly
