HTML Formatter & Minifier
Beautify or compress HTML instantly. Format messy code or minify for production.
When to format? — Use Format mode when working with minified HTML from a CMS, email template, or legacy codebase. Proper indentation makes it readable, debuggable, and maintainable in seconds.
When to minify? — Use Minify mode before deploying static HTML or email templates. Removing whitespace and comments reduces file size by 10–30%, which improves load time and Core Web Vitals.
Script & style blocks — Contents inside <script> and <style> tags are preserved as-is. Use the dedicated CSS Minifier or a JS minifier for those.
Conditional comments — Minify mode keeps <!--[if IE]>…<![endif]--> conditional comments intact even when "remove comments" is checked.
Keyboard shortcut — Press Ctrl+Enter (or ⌘ Enter on Mac) while in the input to run instantly.
