XML Minifier
Strip whitespace between XML tags locally

This strips whitespace between tags; it does not validate well-formedness.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
This tool scans XML-like text locally and removes whitespace-only text between tags and inside opening tags, without building a full DOM tree. It complements the XML Formatter, which does the opposite: it re-indents XML for readability.
How to use it
- Paste XML into the input box, or load the example.
- Review the minified output and the size difference.
- Copy the compact XML for storage or transmission.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my XML uploaded anywhere?
- No. Minifying happens locally in your browser; nothing is sent to a server.
- Are comments and CDATA sections preserved?
- Yes. Comments and CDATA blocks are copied through untouched; only the whitespace between tags is removed.
- Does it validate the XML?
- No. It only strips whitespace; it does not check well-formedness or validate against a schema.
