The HTML Minifier reduces the size of your HTML files by removing unnecessary characters like whitespace, comments, and optional tags. This makes your web pages load faster as the browser needs to download less data.

No. The HTML Minifier operates entirely in your browser. Your code is never sent to our servers, shared with third parties, or stored anywhere. This ensures complete privacy and security for your code.

When used with the default settings, the minifier is designed to preserve the functionality of your HTML. However, if your code relies on specific whitespace formatting or contains conditional comments, you may need to adjust the minification options. Always test your minified HTML to ensure it works as expected.

Minification removes unnecessary characters from your code, making the file smaller. GZIP compression is a server-side technique that compresses files before sending them to the browser. Using both techniques together provides the best results - minify your HTML first, then let your server apply GZIP compression.

It's best to use readable, well-formatted HTML during development for better maintainability. Minification should typically be part of your build process for production. Keep your original HTML files for development and use the minified versions only when deploying to your live site.

According to HTML specifications, certain end tags are optional and can be omitted, including: </li>, </dt>, </dd>, </p>, </option>, </tr>, </th>, </td>, </tbody>, and several others. The HTML Minifier intelligently removes these tags without affecting the rendering of your page.
