What Is HTML Beautification?

HTML beautification reformats messy or minified HTML markup into clean, properly indented code with consistent tag nesting and readable attribute formatting. Well-structured HTML is easier to maintain, debug, and collaborate on. Our beautifier processes your markup entirely in the browser, so template code and proprietary page structures never leave your device.

How to Use HTML Beautifier

    Paste your raw or minified HTML into the input area or upload an .html file.

  2. Select formatting options

    Choose your indentation size, whether to wrap attributes, and other style preferences.

    Click Beautify to format the HTML, then copy it to your clipboard or download the file.

Frequently Asked Questions

Will the beautifier change how my HTML renders in the browser?

No. Beautification only adjusts whitespace and indentation. The DOM structure and visual rendering of your HTML remain unchanged, with the exception of pre-formatted content which is preserved as-is.

Does it handle inline CSS and JavaScript within HTML?

Yes. The beautifier detects embedded style and script blocks and formats them according to their respective language conventions while maintaining proper HTML structure.

Can I use the beautifier with template languages like EJS or Handlebars?

The tool works best with standard HTML. Template syntax is preserved as-is, though indentation around template blocks may need minor manual adjustments for complex template logic.
