About HTML Formatter — Beautify & Minify HTML Online
HTML copied from a page source, a build output, or a scraper is often one long unreadable line — or so deeply nested you can't follow the structure. This free HTML formatter re-indents that markup into clean, readable code with its beautifier, and the minifier does the reverse: stripping comments and whitespace to shrink pages for production.
Beautify pretty-prints nested elements and keeps every attribute exactly as written. Minify HTML by collapsing whitespace, removing comments, and compressing inline CSS and JavaScript. Both run entirely in your browser — your markup is never uploaded, so it's safe for private templates and internal pages.

Frequently asked questions
What is the difference between beautify and minify?
Beautify adds indentation and line breaks so HTML is easy to read and edit. Minify removes that whitespace plus comments and compresses inline CSS and JavaScript, producing the smallest valid markup for faster page loads.
Does it change my inline scripts and styles?
Beautify leaves inline script and style bodies intact while indenting the surrounding HTML. Minify will compress inline CSS and JavaScript to save bytes, but does not alter their behaviour.
Is my HTML sent to a server?
No. All formatting happens locally in your browser. Nothing you paste is uploaded, logged, or stored, so it is safe for private and proprietary markup.
Can it handle messy or generated HTML?
Yes. It is built for cleaning up scraped, exported, or machine-generated markup. It does its best on imperfect input and reports a clear message if something cannot be parsed.
