About XML

XML is a markup format for structured documents and data, still common in SOAP APIs, RSS feeds, Android resources, Maven builds and enterprise integrations. Elements can carry attributes as well as child elements.

Private by design

Developer data is often sensitive: API responses, tokens, customer records, internal configs. This XML Minifier processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
