HTML Beautifier
Formats HTML source for readability.

What HTML Beautifier does
The HTML Beautifier formats unformatted or minified HTML into a structured, readable version. Users paste their source code into the interface, and the tool applies indentation, line breaks, and spacing to make the markup easier to read and debug. The output preserves all original content while applying consistent formatting rules. The site offers a clean interface with options to adjust indentation style, whitespace amount, and section preferences, then displays the formatted result instantly. Additional actions include copying, downloading, or opening the beautified HTML in a new tab.
