HTML Minifier

Strip comments and whitespace from your markup without losing readability, then copy the optimised HTML instantly.

Drag HTML here or to populate the editor.

The preview refreshes automatically as the markup changes.

Minification hints

Ensure HTML is valid before minifying; malformed markup can lead to unexpected rendering.
Inline scripts and styles are preserved—consider externalising large blocks for better caching.
Whitespace inside <pre> and <code> blocks is significant and retained.
