Question 1

What does XML minification remove?

Accepted Answer

XML minification removes whitespace between elements, newlines, indentation, and XML comments. It collapses all the space that was added for human readability, producing a compact single-line XML document. All element names, attributes, values, CDATA sections, and XML declarations are preserved exactly. The resulting XML is semantically identical to the original.

Question 2

Can I minify SVG files?

Accepted Answer

Yes. SVG files are valid XML and can be minified using PureFormatter's XML minifier. Minifying SVG removes whitespace and comments, which can reduce SVG icon file sizes by 20–40%. For more aggressive SVG optimization including attribute removal and path simplification, use SVGO — a dedicated SVG optimizer. PureFormatter is ideal for basic whitespace-based SVG compression.

Question 3

Does minifying XML affect how it's parsed?

Accepted Answer

No. XML parsers ignore whitespace between elements when processing XML data. The minified document produces the exact same DOM tree as the formatted original. CDATA section content is preserved as-is since whitespace inside CDATA is significant. Whitespace inside element text content that is meaningful is also preserved.

Question 4

Should I minify XML for RSS or Atom feeds?

Accepted Answer

Minifying RSS or Atom feeds reduces their size, which speeds up polling by feed readers. However, the improvement is modest compared to enabling gzip compression on your server, which is more impactful and easier to configure. If your server already serves gzip-compressed responses, XML minification provides diminishing returns. It is still a worthwhile optimization for very large feeds with many entries.
