Beautify and indent your HTML code for improved readability and easier debugging.
The HTML Formatter is a free online tool that takes messy or minified HTML and transforms it into a clean, properly indented structure. It parses your markup tag by tag, tracking nesting depth to apply consistent indentation, making it easy to read and understand the document hierarchy at a glance.
Developers frequently encounter minified or poorly formatted HTML when inspecting third-party code, debugging templates, or working with auto-generated markup. This tool lets you quickly restore structure and readability without manually adding line breaks and spaces, saving valuable development time.
Paste your HTML into the input field, choose your preferred indent size, and click the format button. The formatter handles void elements like img and br correctly, and processes everything client-side so your code stays private. The formatted output appears instantly and can be copied with one click.
Whether you're cleaning up a single snippet or formatting an entire page template, this tool delivers consistent, readable output every time. No signup, no limits — just paste, format, and copy.
