Format messy HTML into clean, indented code, or minify it for production — all in your browser, free, with nothing uploaded.
HTML formatting (also called beautifying or prettifying) takes unformatted HTML code and applies consistent indentation, line breaks, and spacing. Well-formatted HTML is easier to read, debug, and maintain, especially in large projects with complex nested structures.
Format (Beautify): Adds proper indentation (2 spaces per level), line breaks between tags, and consistent spacing. Best for development, debugging, and learning.
Minify: Removes all unnecessary whitespace, line breaks, and comments. Reduces file size by 20-50% for faster page loads in production.
