XML Minifier
Compact XML payloads for fixtures, logs, and transport while keeping parsing errors visible.
Input
Paste XML to minify
Output
Minified XML output
Paste well-formed XML, then choose Minify XML.
How XML minification works
The minifier parses XML with the browser parser, removes formatting whitespace, and serializes elements back to a compact XML string.
Invalid XML
Malformed XML shows a parser error and keeps the output empty so broken payloads are not copied by mistake.
What this XML Minifier does
Use this XML minifier to compact well-formed XML by removing unnecessary whitespace between elements. It is helpful for shrinking payload examples or preparing XML for transport.
When developers use it
- Compact formatted XML into a smaller single-line payload.
- Validate that XML is well-formed before sharing or embedding it.
- Create copy-ready XML output from browser-local input.
Privacy, input, and output
Minification happens locally in the browser. The XML text is not uploaded by PayloadHarbor.
Paste XML and run Minify. The tool parses the document first, then emits compact XML if there are no parser errors.
Validation rules and limitations
- Input must be well-formed XML.
- Whitespace inside text nodes may be normalized during compaction.
