What Is HTML Formatter and Beautifier?

The HTML Formatter and Beautifier is a free, browser-based online tool designed to clean up, organize, and beautify raw or minified HTML code. Whether you're a novice just beginning your web development journey or a seasoned developer managing large-scale web projects, this tool helps you convert unformatted or messy HTML into clean, readable, and well-structured code instantly.

An HTML formatter — sometimes referred to as a “pretty printer” or “beautifier” — processes your HTML markup and applies a consistent indentation style. This improves readability, maintains coding standards, and greatly simplifies editing, debugging, and collaboration.

If you’re dealing with compressed HTML code (often the result of minification or pasting from various online tools), this formatter restores structure to your code by adding appropriate line breaks, indentations, and spacing — turning cluttered code into clear, professional-grade markup.
