HTML Minifier

HTML minification is the process of removing all unnecessary characters from your HTML code without changing how it works. This includes things like whitespace, line breaks, comments, and sometimes optional closing tags or attribute quotes.

The goal is to make your HTML file as small as possible so it downloads faster. Even small reductions can add up when you're serving thousands of page views.

Minifying your HTML has a few real benefits for your website.

• Faster page loads. Smaller files transfer faster over the network. This is especially noticeable on mobile connections where every kilobyte counts.
• Better Core Web Vitals. Google uses page speed as a ranking factor, and minification helps improve metrics like Largest Contentful Paint and Time to First Byte.
• Lower bandwidth costs. If you're paying for bandwidth, smaller files mean lower bills. This really adds up at scale.
• Improved user experience. Nobody likes waiting for a page to load. Faster sites keep visitors happy and reduce bounce rates.

This tool can remove several types of unnecessary content from your HTML.

• HTML comments. Those notes you leave for yourself or other developers are helpful during development but add bytes in production.
• Extra whitespace. Multiple spaces, tabs, and indentation get collapsed down to single spaces or removed entirely where they're not needed.
• Line breaks. Newlines between tags don't affect how the page renders, so they can usually be removed safely.
• Unnecessary quotes. Attribute values that don't contain spaces or special characters can often work without quotes, though this is optional since some developers prefer to keep them.

The tool is careful not to touch whitespace inside pre, code, textarea, or script tags since that whitespace is often meaningful.

Yes, minified HTML is completely safe. The minification process only removes characters that browsers ignore anyway. Your page will look and function exactly the same.

That said, minified code is hard to read and debug. Most developers keep their original, readable source files and only minify when deploying to production. If you need to make changes later, you can use the "Beautify HTML" option to make the code readable again.

The reduction depends on how your original HTML is formatted. Code with lots of comments, indentation, and blank lines will see bigger savings. Typical reductions range from 10% to 30%.

For example, a 50KB HTML file might shrink to 35KB after minification. Combined with gzip compression on your server, you could see total reductions of 70% or more compared to uncompressed, unminified HTML.

The tool shows you exactly how many bytes you saved and the percentage reduction so you can see the impact right away.
