Frequently Asked Questions
Will this HTML minifier break script or style blocks?
The tool protects script, style, pre, and textarea blocks before minification, then restores them to avoid accidental whitespace loss in those sections.
Why minify HTML for SEO and performance?
Smaller HTML payloads can reduce transfer size and improve render speed, which contributes to better user experience and technical SEO quality.
Can I copy and download minified output?
Yes. You can copy minified HTML to clipboard or download it as an HTML file for deployment.
