Compress XML by removing all whitespace, line breaks, and comments. Reduce XML payload size instantly. All minification runs locally in your browser.
XML minification removes all unnecessary whitespace — spaces, tabs, newlines — and optionally strips XML comments from a document, producing the smallest possible valid XML that still carries all the original data. Minified XML is faster to transmit over HTTP, cheaper to store, and occupies less memory when loaded into a parser.
JSON Viewer Pro's XML minifier validates your XML first, then removes all insignificant whitespace between tags and collapses internal whitespace. Comments are also stripped since they have no effect on parsed data. The result is a compact, single-line XML string ready for production use, embedding in code, or storing in a database.
All XML minification runs locally in your browser — nothing is uploaded to a server. This makes it safe to minify XML containing API keys, database connection strings, or other sensitive configuration values.
No. Only insignificant whitespace and comments are removed. All element data, attributes, and structure remain the same.
Typically 20–60% depending on how much indentation and whitespace the original contains.
Yes. Minified XML is fully valid XML that any XML parser will accept.
