HTML Minifier
Strip unnecessary whitespace, line breaks, HTML comments, and redundant attributes from your HTML source code to produce a smaller, faster-loading file. Minifying HTML is a standard web performance optimization technique that reduces the number of bytes browsers need to download, helping pages load faster and improving your Core Web Vitals scores. This tool is ideal for web developers preparing HTML for production deployment, optimizing landing pages, or reducing server bandwidth costs. The minified output is functionally identical to the original — just without the formatting overhead that browsers do not need.

Frequently Asked Questions
Is minified HTML still valid HTML?
Yes. Minification only removes whitespace and comments — it does not alter any HTML tags, attributes, or content. The output renders identically in all browsers.
How much does HTML minification reduce file size?
Typical HTML files see a 10–30% size reduction from minification. Pages with extensive comments or pretty-printed code can see reductions of 40% or more.
Does minification break inline JavaScript or CSS?
Our HTML minifier is careful to preserve inline script and style content. However, for best results you should also minify your CSS and JavaScript files separately using the CSS Minifier and JS Minifier tools.
Can I undo minification?
Minification removes formatting and is not directly reversible to your original layout. Always keep a copy of your original formatted source code before minifying.
