HTML Beautifier

Format and indent HTML markup for readability. Properly nests tags with consistent indentation.

The formatter handles standard HTML elements including self-closing tags, void elements, and nested structures. Choose your preferred indent size from 1 to 8 spaces. Everything runs in your browser.
