HTML Formatter & Minifier
Paste raw HTML below to either beautify it into clean, indented markup for readability, or minify it into a compact single block for production.
How to Use the HTML Formatter & Minifier
- Paste your HTML markup into the input box.
- Click "Beautify" to re-indent it by tag depth for readability, or "Minify" to strip comments and collapse whitespace for a smaller file size.
- Void elements like
<br>,<img>,<input>and<hr>are handled correctly and never get an extra closing indent. - Click "Copy" to copy the result to your clipboard.
Why Use This Tool?
Is my HTML uploaded anywhere?
No. Both beautifying and minifying run entirely as plain JavaScript in your browser. Nothing you paste is sent to a server, which matters if you're formatting a work-in-progress page that includes internal links, draft copy, or embedded API keys in script tags.
What does minifying actually remove?
Minifying strips HTML comments (<!-- ... -->) and collapses all whitespace between tags into nothing, shrinking file size for faster page loads. It does not rewrite attribute values or remove functional whitespace inside inline <pre>/<script> content in a way that changes rendering for typical markup.
How does the beautifier handle nested tags?
It walks the markup tag by tag, increasing the indentation level after each opening tag and decreasing it after each matching closing tag, while correctly recognizing self-closing and void elements (like <meta>, <link>, <input>) so they don't incorrectly increase the nesting depth.
Who uses an HTML formatter?
Developers cleaning up markup pasted from a CMS or email template, students learning HTML structure, and anyone preparing a production build who wants to shave a few kilobytes off a page's HTML payload before deployment.
