About This Tool
Why use HTML Minifier?
Strips comments, collapses runs of whitespace and removes the space between tags, then reports how much smaller the result is. On a typical hand-written page that is a 10–25% reduction before compression.
The saving after gzip or brotli is smaller, because compression already handles repeated whitespace well — but minification still cuts parse work and bytes over the wire. Be careful with content where whitespace is significant: <pre>, <textarea> and inline elements separated by a deliberate space can change appearance, so check the output before shipping.

HTML Minifier FAQs
How much does minifying HTML save?
Usually 10–25% of the raw file size, less once gzip or brotli is applied since compression already handles repeated whitespace.
Can minification break my page?
It can where whitespace is meaningful — inside <pre> or <textarea>, or between inline elements that rely on a space to separate them. Always check the rendered result.
Is it better to minify or to enable compression?
Compression matters more; do that first. Minification is a smaller additional gain that also reduces parsing work.
Does minified HTML help SEO?
Only indirectly, through slightly faster loading. Page speed is a ranking signal, but a few kilobytes of whitespace is rarely what makes a page slow.
