XML Minifier
Remove unnecessary whitespace from XML to make it as compact as possible.
This XML Minifier removes unnecessary whitespace — indentation and line breaks between tags — to shrink an XML document's size without changing its structure or content. Paste XML or upload an .xml file, click Minify, and see the byte-size reduction. All processing happens locally in your browser; your XML is never uploaded.
How to use
- 1Paste XML into the input, or upload an .xml file.
- 2Click Minify to remove all unnecessary whitespace.
- 3Copy or download the result — the size reduction is shown for reference.
Frequently asked questions
What gets removed when minifying XML?
Whitespace between tags used purely for indentation — the actual element and attribute content is untouched, so the document means exactly the same thing to any XML parser afterward.
Why would I minify XML?
Reducing payload size for an API response, shrinking a config file before deploying it, or preparing XML for a system with strict size limits.
Will minifying break my XML?
No, as long as the input was well-formed to begin with — whitespace-only formatting text isn't part of the document's meaning, so removing it doesn't change how the XML parses.
Is my file processed on a server?
No. Minification happens locally in your browser tab — your XML is never uploaded.
