HTML Minifier & Beautifier Online
Minify HTML to reduce file size or beautify compressed HTML for readability. Free online HTML formatter and compressor.
What is HTML Minification?
HTML minification is the process of removing unnecessary characters from HTML source code without changing its functionality. This includes stripping whitespace, line breaks, comments, and other non-essential characters. The result is a smaller file that browsers download faster, directly improving page load time and Core Web Vitals scores.
What does this tool remove?
The minifier removes HTML comments, collapses consecutive whitespace between tags, and trims leading/trailing spaces from each line. IE conditional comments (<!--[if IE]>...<![endif]-->) are preserved since they affect browser behavior.
When to use HTML Beautify?
Beautifying HTML adds proper indentation and line breaks, making the markup much easier to read and maintain. It is useful when you receive a minified HTML file and need to understand or debug its structure. You can choose between 2-space, 4-space, or tab indentation to match your coding style.
How much can HTML be compressed?
Typical HTML files can be reduced by 10–30% through minification alone, depending on how much whitespace and how many comments the original file contains. When combined with server-side Gzip or Brotli compression, total transfer size reductions of 60–80% are common. Most modern web servers and CDNs apply text compression automatically, so minification provides an additional layer of savings.
