How it works
Convert in three steps

Paste or drop

Paste your HTML or drop up to 15 .html files. Choose Beautify or Minify and set your indent size.

Format

Click Format. The tool re-indents nested elements correctly, preserves the contents of script, style, pre, and textarea, and highlights the result.

Copy or download

Copy the formatted markup or download it as an .html file. Processing is fully local.

FAQ
Common questions

No. Beautifying only adjusts whitespace and indentation between tags — the structure and content are preserved, so the rendered output stays identical.

Yes. The contents of script, style, pre, and textarea are treated as raw and left untouched, so your inline JavaScript, CSS, and pre-formatted text aren’t reindented or broken.

Minify removes comments and collapses whitespace between elements to reduce file size, while keeping raw blocks intact — useful for shipping smaller HTML to production.

Never. Formatting and highlighting run entirely in your browser, so even unreleased markup and templates stay private.

About the HTML Formatter / Beautifier

A clean, consistently indented HTML document is far easier to read, review, and debug than a minified or hand-tangled one. This formatter parses your markup, re-indents nested elements with your chosen indent style, and renders a colour-highlighted preview so structure is obvious at a glance. When you’re ready to ship, the same tool minifies — stripping comments and inter-tag whitespace — to trim bytes off the page.

Benefits
Privacy

Everything is processed client-side. Your HTML is parsed and formatted in the browser with no uploads, no storage, and no external requests — making it safe for proprietary templates and pre-launch pages.
