HTML formatter
WEBFree online HTML formatter and beautifier that indents, cleans, and minifies HTML markup right in your browser.
What is the HTML formatter tool?
This HTML formatter turns messy or minified markup into clean, consistently indented HTML you can actually read — free, with no sign-up, and processed entirely in your browser. Paste a fragment or a whole page, click Beautify, and the tool re-indents every element so the nesting is obvious at a glance. Syntax highlighting makes the structure easy to scan while you work, and when you are done you can copy the result or download it as an .html file.
The same tool works in reverse: choose Minify to strip comments and insignificant whitespace and compress your markup for production — the same engine that powers Carbide's dedicated HTML minifier page. Either direction, the contents of script, style, pre and textarea blocks are preserved verbatim, so inline JavaScript, CSS and pre-formatted text come through untouched instead of getting mangled the way aggressive formatters sometimes do.
Because everything runs client-side, your code never leaves your device — no server round-trip, no logs, no copy of your markup anywhere but your own machine. That makes it safe to beautify HTML from client projects and internal tools, and it is why the page keeps working offline once loaded. Compared with the ad-heavy formatter sites, it is a fast, quiet way to clean up exported templates, debug deeply nested layouts or prettify HTML from a CMS — on desktop or on your phone.
How to use the HTML formatter

- Click Beautify to re-indent the markup with clean, consistent nesting.
- Or click Minify to strip comments and whitespace for a compact file.

Frequently asked questions
Beautify vs minify — what's the difference?
Beautify adds indentation and line breaks so the markup is easy to read and edit; minify removes comments and insignificant whitespace so the file is as small as possible for production. This tool does both — and you can round-trip: minified HTML can always be beautified back into readable form.
How do I format HTML online?
Paste your markup into the editor and click Beautify. The tool re-indents every element instantly in your browser — no upload, no account, no waiting on a server.
Will formatting break my inline scripts or styles?
No. The contents of script, style, pre and textarea blocks are preserved exactly as written, so embedded JavaScript, CSS and pre-formatted text stay intact after beautifying or minifying.
Is my HTML uploaded to a server?
No. Formatting happens entirely on your device in the browser. Your markup never leaves your computer, which makes the tool safe for private and client code, and it works offline once the page has loaded.
What does an HTML beautifier actually do?
It parses your markup and re-prints it with consistent indentation, one logical element per line, so the nesting structure becomes visible. It changes only whitespace and layout — the rendered page stays identical.
Is the HTML formatter free?
Yes, completely — no sign-up, no watermark and no limit on how much HTML you format or minify.
