    About XML Minifier

    Everything you need to know about this tool and how to get the most out of it.

    What is XML Minifier?

    What is XML Minifier?

    The XML Minifier is a browser-based tool that compresses XML files by removing all unnecessary whitespace between tags. Unlike simple text-based minifiers, it uses the browser's native XML parser to validate your XML first, ensuring the output is always well-formed.
    How XML Minifier Works

    How XML Minifier Works

    The tool parses your XML using the browser's built-in `DOMParser`, which validates the structure. If the XML is valid, it re-serializes it using `XMLSerializer` and then removes all whitespace between closing and opening tags (> <). This produces a compact, single-line XML string.
    Why Use XML Minifier?

    Why Use XML Minifier?

    XML is widely used for data interchange, configuration files, RSS feeds, and sitemaps. Minifying XML reduces its size for faster transmission over networks and less storage usage. The built-in validation step also helps catch syntax errors before they cause problems in production.
