When Should You Convert WEBP to AVIF?
Upgrading web infrastructure
You optimized your images to WebP a few years ago and got good results. Now browser support for AVIF has matured, and you can squeeze another 20-30% off those file sizes. For high-traffic sites, that's a significant bandwidth and cost reduction.
Photography websites
AVIF's HDR and wide color gamut support makes it the superior choice for photo galleries and portfolio sites. Colors pop, gradients are smoother, and dark areas retain more detail compared to WebP.
CDN optimization
More images means higher CDN costs. AVIF's smaller file sizes reduce bandwidth consumption and transfer fees. For sites serving millions of images per month, the savings from switching from WebP to AVIF are substantial.
Mobile app assets
Mobile apps that load images over cellular connections see real performance gains from AVIF. Smaller images mean faster rendering, less data usage, and happier users on limited data plans.
