HTML Formatter — Beautify, Indent & Minify HTML
Turn messy or minified HTML into clean, readable markup — or compress it for production.
Quick answer
To format HTML, paste your code into the KaviForge HTML Formatter and it is beautified instantly with consistent indentation. Choose 2 spaces, 4 spaces, or tabs. Click "Minify" to remove comments and whitespace between tags for a smaller file.
HTML copied from a CMS, email builder, browser DevTools, or a minified build is often one long line or badly indented. Formatting it makes the structure of nested elements obvious and bugs easier to find.
This formatter uses the proven js-beautify engine to indent elements, keep inline content readable, and format embedded CSS and JavaScript inside style and script tags.
How to Format HTML
- 1Paste your HTML into the input box, or upload an .html file.
- 2Choose the indentation: 2 spaces, 4 spaces, or tabs.
- 3Read the beautified HTML in the output box — it updates as you type.
- 4Click "Minify" instead to compress the HTML.
- 5Copy the result or download it as formatted.html.

About the HTML Formatter
Beautifying uses js-beautify’s HTML formatter, loaded on demand so the page stays fast. Minify mode removes HTML comments (except conditional comments) and collapses whitespace between tags.
The minifier is intentionally conservative. Whitespace inside pre and textarea elements can be significant, so review minified output if your page relies on it.
