Frequently Asked Questions

Minification reduces file size by removing unnecessary characters. Smaller HTML means faster page loads, lower bandwidth usage, and better Core Web Vitals scores.

Yes for production HTML. HTML comments are invisible to users and serve only development purposes. Conditional comments used for old IE browsers are also safe to remove in modern web projects.

Some HTML tags are optional per the spec (e.g. closing </li>, </p>, </tbody>). Browsers can infer them. Removing them saves bytes, but some parsers or tools may require them.

Minification typically reduces HTML size by 10-25%. Combined with gzip/brotli compression on the server (which further reduces by 60-80%), the total savings can be significant for large pages.
