HTML formatter

What it does

The Carbide HTML formatter tidies messy or minified HTML into clean, readable markup with consistent indentation, and can compress it back to a single compact line when you need the smallest possible file. It is completely free, runs entirely in your browser, and is offline-friendly once the page has loaded, so your code never leaves your device and nothing is ever uploaded to a server. Paste a fragment or a whole page into the editor, pick beautify for clear nesting or minify to strip comments and insignificant whitespace, then copy the result or download it as an .html file. Syntax highlighting makes structure easy to scan while you work, and the tool preserves the contents of script, style, pre, and textarea blocks so nothing important gets mangled. Whether you are cleaning up exported templates, debugging deeply nested layouts, or shrinking output for production, the HTML formatter gives you a fast, private way to get well-organized markup in seconds.

Frequently asked questions

Is the HTML formatter free to use?

Yes. Every Carbide tool is free with no sign-up, no watermarks, and no limits on how much HTML you format.

Does my HTML get uploaded anywhere?

No. Formatting happens entirely in your browser using on-device processing, so your markup never leaves your computer and works even offline once loaded.

What is the difference between beautify and minify?

Beautify adds consistent indentation and line breaks for readability, while minify removes comments and insignificant whitespace to produce the smallest possible file.

Will it break my inline scripts or styles?

No. The tool preserves the contents of script, style, pre, and textarea blocks verbatim so your code and pre-formatted text stay intact.
