Speed Up Your Website with HTML Minification

HTML minification removes unnecessary characters from your HTML code without changing its functionality. This includes whitespace, line breaks, comments, and optional closing tags. Minified HTML files are smaller, which means faster download times for your visitors and better Core Web Vitals scores.

Every kilobyte matters for page load performance, especially on mobile networks. By minifying your HTML, you reduce the amount of data that needs to be transferred over the network, directly improving your Time to First Byte (TTFB) and First Contentful Paint (FCP) metrics.

FAQ

Will minification break my HTML?
No. Minification only removes whitespace and comments — it does not alter your HTML structure, tags, or attributes. The output is functionally identical to the input.
How much space does minification save?
Typically 10-30% depending on how well-formatted the original code is. Code with lots of comments and indentation will see larger savings.
