Why Format HTML? Beautify vs Minify

Properly formatted HTML improves readability, makes debugging easier, and helps with code reviews. Beautify is used during development to work with clean code. Minify is used for production to reduce file size and improve load time. Typical workflow: develop with beautified code, minify before deploying.

Frequently Asked Questions

Does it support JSX/React components?

This tool is optimized for plain HTML. JSX has syntax differences (className instead of class, camelCase attributes). For JSX, use Prettier with the JSX plugin or VS Code's built-in formatter.

Does minify remove comments?

No, the minify function only removes whitespace and line breaks, preserving comments. For full minification including comment removal, use a build tool like html-minifier.

Is my code uploaded to a server?

No. All processing happens 100% in your browser. Your code never leaves your machine. You can verify this by checking the Network tab in DevTools.

What indentation style does it use?

The beautifier uses 2 spaces per indentation level, which is the most common standard for HTML. This is not currently configurable.

Can it handle malformed HTML?

The tool does its best with malformed HTML but may produce unexpected results. For best output, start with valid HTML structure.
