When to Use Responsive Asset Delivery
Serving desktop-sized images to mobile devices wastes bandwidth and kills performance. Responsive asset delivery ensures every visitor gets images optimized for their specific screen-faster loads, better Core Web Vitals, higher conversions.
- ✓ Your mobile pages load slower than desktop
- ✓ Core Web Vitals scores need improvement
- ✓ You have image-heavy landing pages
- ✓ Mobile bounce rates are high due to slow loading

Frequently Asked Questions
Does this replace srcset?
It works alongside srcset. ConversionWax handles content personalization; you can still use native responsive images for basic optimization.
How much faster will my pages load?
Depends on your current setup. Teams typically see 30-60% reduction in image payload for mobile, translating to 1-3 second faster loads.
Do I need to create multiple image versions?
Yes-you upload the variants you want to serve. ConversionWax handles the logic of which to show when.
Will this help Core Web Vitals?
Yes. Smaller images improve LCP (Largest Contentful Paint), a key Core Web Vitals metric.
Can I combine responsive assets with A/B testing?
Yes. Test different image approaches per device to find what converts best.
Does this affect SEO?
Positively. Faster page speeds and better Core Web Vitals improve search rankings.
