The WebToolsLab HTML Minifier helps you minify HTML online by removing extra whitespace, comments, and redundant characters. Smaller HTML files load faster, improve Core Web Vitals, and boost SEO β with no change to how your page renders. Everything runs client-side for privacy; your code never leaves the browser.
The minifier parses your HTML and removes non-essential characters like spaces, line breaks, tabs, and comments.
It also tightens gaps between tags (e.g., > <
β ><
) while keeping attributes,
text content, and semantics intact.
