HTML Formatter & Minifier – Free Online Tool

HTML Formatter

Turn messy HTML into clean, readable code — or minify it for production with one click.

🔒 Private: everything runs in your browser. The simple minifier collapses whitespace between tags — it skips minifying when your code contains <pre>, <textarea> or inline <script>, because whitespace matters there.
