Frequently Asked Questions
Quick answers to common questions
What is code minification?+
Minification removes unnecessary characters from code (whitespace, comments, newlines) without changing its functionality. It reduces file size, speeding up web page loads.
Does minifying HTML affect SEO?+
Minifying HTML correctly has no negative SEO impact. It can improve Core Web Vitals (LCP, FID) by reducing page load time, which can positively affect rankings.
Should I minify CSS in production?+
Yes, always. A production build pipeline (webpack, Vite, Parcel) should auto-minify CSS. If you're on a static site without a build step, use this tool to manually minify before uploading.
