TL;DR
Use HTML responsive images to adjust quality based on screen resolution. Take advantage of modern formats like WebP and AVIF, and integrate lazy loading to enhance performance.
❓ Frequently Asked Questions

Le lazy loading ralentit-il l'affichage?
Non, il améliore la vitesse perçue de la page en chargeant les images uniquement lorsque le visiteur les atteint dans leur navigation.
Les images responsives sont-elles compliquées à gérer?
Elles peuvent nécessiter des ajustements techniques et des tests, notamment pour garantir la compatibilité sur tous les navigateurs et dispositifs, ce qui peut être complexe sans expertise.
