HTML minifier
Free HTML Minifier — Shrink Your HTML by Removing Waste
This tool minifies your HTML by stripping out the characters that browsers don't need — extra whitespace, line breaks, comments and redundant formatting. Paste your HTML and get back a smaller, functionally identical version that loads faster and transfers fewer bytes.
Minification is a simple, safe optimization with a direct performance payoff. The whitespace and comments that make source code readable for humans add nothing for the browser, but they still have to be downloaded by every visitor. Removing them shrinks the file, which means faster transfer and faster rendering — small per page, but meaningful at scale, and it stacks neatly on top of server compression like Brotli or Gzip. Faster pages feed straight into better Core Web Vitals and a smoother experience for users on slow connections.
Use this tool to minify HTML before deploying, to quickly compress a static page or template, or to see how much weight your markup is carrying. For a quick manual optimization it's ideal; for larger projects, the same result is best achieved automatically as part of your build pipeline so every deploy ships minified by default. Either way, sending leaner HTML is one of the easiest speed wins available.
