XML Minifier
NewMinify XML by removing whitespace and comments to reduce file size.
Frequently Asked Questions
What exactly gets removed when I minify XML here?
The tool strips comment nodes, removes whitespace-only text nodes, and then collapses gaps between tags. Text content stays intact, but formatting whitespace is discarded.
Does it preserve the XML declaration at the top?
Yes. If the source starts with an XML declaration, the output keeps it and appends the minified XML body right after it.
Why is the size reduction smaller than I expected?
This minifier only removes comments and formatting whitespace. It does not shorten tag names, attributes, or text values, so already-compact XML will not shrink much.
Can I download the minified file directly?
Yes. The Download button saves the current output as minified.xml using an application/xml blob.
Why is the output blank after I click Minify?
That happens when the XML does not parse cleanly. The tool refuses to minify invalid XML and shows the browser parser error instead.
