Free online XML beautifier. Format, prettify and indent XML instantly in your browser with customizable options.
What is an XML beautifier?
An XML beautifier is a tool that reformats XML code to make it more readable by adding proper indentation, line breaks, and spacing while preserving the document structure.
How does XML beautification work?
The tool parses the XML input into a document tree, then re-serializes it with configurable indentation (spaces or tabs) and proper line breaks between elements.
Is my XML data safe?
Yes. All processing happens entirely in your browser. Your XML data is never sent to any server, ensuring complete privacy and security.
Can I customize the indentation?
Yes, you can choose the number of spaces for indentation, typically 2 or 4 spaces per level, to match your coding style preferences.
Does this tool validate XML?
Yes, the beautifier will detect and report XML syntax errors during formatting, helping you identify issues in your XML documents.
What is XML used for?
XML (eXtensible Markup Language) is used for data storage, configuration files, web services (SOAP), sitemaps, RSS feeds, and data exchange between systems.
Can I beautify large XML files?
Yes, the tool handles large XML files efficiently since all processing runs locally in your browser without any file size limitations.
What is the difference between XML beautifier and XML minifier?
A beautifier adds whitespace and indentation for readability, while a minifier removes all unnecessary whitespace to reduce file size for production use.
Does it preserve XML comments and CDATA?
Yes, the beautifier preserves all XML comments, CDATA sections, processing instructions, and the original document structure.
Can I use this tool offline?
Yes, once the page is loaded, all XML processing happens locally in your browser without requiring an internet connection.
What XML versions are supported?
The tool supports XML 1.0 and XML 1.1 documents, including proper handling of namespaces, attributes, and special characters.
How is XML different from HTML?
XML is designed to store and transport data with user-defined tags, while HTML is designed to display data with predefined tags. XML is stricter in syntax requirements.
How to Use XML Beautifier
Format or compress XML instantly in your browser. Beautify messy markup into readable, indented form or minify it for compact storage — everything stays on your device.
- Paste your XML into the editor — the placeholder hints at the expected input: <root><item>Hello</item></root>.
- Under “Action:”, select Beautify to format and indent, or Minify to strip whitespace.
- Set “Indent:” to 2 Spaces, 4 Spaces, 8 Spaces or Tab to control the nesting style.
- Copy the processed result from the output panel for use in configs, logs or APIs.
Choose Tab indentation when humans will edit the XML by hand; 2 Spaces keeps diffs and version history compact.
