What is XML?

XML (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML is widely used for data storage, configuration files, and data exchange between systems.

File Size Limitations

Recommended file sizes for best performance:

• Under 2MB: Works perfectly with instant formatting
• 2-5MB: Works well, may take a few seconds
• 5-10MB: May cause browser slowdown, but usually works
• Over 10MB: Not recommended - may freeze or crash your browser

This tool processes everything in your browser's memory. Very large XML files may cause performance issues or browser crashes. For files over 10MB, consider using command-line tools or server-based processors.

Privacy & Security

This tool runs entirely in your browser using JavaScript. Your XML data is never transmitted to any server. All formatting, validation, and minification operations are performed locally on your computer.
