100% client-side — your code never leaves your browser.

Is my code sent to a server?: No. All minification happens locally in your browser. Your code is never uploaded or stored.
Will minification break my HTML?: The minifier preserves content in pre, script, style, and textarea tags. It only removes unnecessary whitespace and comments from the rest of the document.
What are "optional closing tags"?: In HTML5, certain closing tags like </li>, </p>, </td> are optional. Removing them reduces file size without affecting how browsers render the page.
How much file size reduction can I expect?: Typical HTML files see 10–30% size reduction depending on the amount of whitespace and comments in the original code.
