About This Tool
The HTML Beautifier takes compressed, single-line, or poorly formatted HTML and reformats it with clean indentation and consistent line breaks. Tags are properly nested and indented to reflect the DOM hierarchy, making the structure easy to read and understand.
Inline elements and void elements (like br, img, input) are handled correctly. Script and style blocks retain their content. The indentation size can be set to 2 or 4 spaces depending on your preference.
Use this tool to clean up minified HTML from production builds, format template output for review, or tidy up HTML before committing to version control. Runs entirely in the browser — no data is sent anywhere.
