Frequently asked questions

## Image optimization FAQ.

The short version of how the pipeline works and why it affects UX and search visibility.

## Frequently asked questions

**How does it differ from generic tools?**

Generic tools apply the same rules to every file. We tune format, dimensions, compression and usage context to cut weight without degrading the visual detail that drives trust and conversion.

**What is the advantage of AVIF over WebP?**

AVIF usually offers 20-30% better compression than WebP at the same visual quality, and handles textures and fine detail in product images better.

**Does this affect SEO?**

Yes. Image weight is a common cause of poor LCP. Reducing weight improves Core Web Vitals, mobile experience and technical search signals.
