What is XML Minifier?
An XML minifier removes all unnecessary whitespace from XML documents — indentation spaces, line breaks between elements, and trailing whitespace within text nodes — to produce the smallest possible valid XML representation. Minified XML is functionally identical to the formatted version but significantly smaller in file size, which reduces bandwidth consumption, improves API response times, and decreases storage costs. This is particularly important for high-volume XML data exchange, SOAP services with large message payloads, and RSS/Atom feed delivery to many subscribers. The tool reports the exact number of bytes saved and the percentage reduction.
