Frequently Asked Questions

Are my images uploaded to a server?

No. All image compression runs 100% locally in your browser using Web Workers. Your files are never transmitted to or stored on any external server.

Why does compressing images improve SEO?

Large unoptimized images slow down page load speeds and hurt Google's Largest Contentful Paint (LCP) metric. Compressing images reduces bandwidth usage and boosts both Core Web Vitals and search rankings.
