Validate XML instantly
This free XML minifier checks syntax first so invalid XML is flagged before the output is compressed.
Minify XML for compact output
Once XML is valid, the tool removes unnecessary formatting whitespace and produces a compact output for sharing or storage.
Useful for feeds and configs
Minified XML can be handy when preparing feeds, configuration data, or examples that need to stay compact.
Helpful for quick transport
Smaller XML output is easier to copy into tools, logs, or test environments where extra whitespace is not needed.
Displays validation issues
If the XML has a parsing problem, the tool shows that issue instead of generating a minified result from broken markup.
