Why This Is 2026 Gold Standard 🔥

AVIF first → maximum compression + HDR quality for ~95–98% of users 👑
WebP second → still tiny files for almost everyone else
Multiple widths (srcset) → browser downloads only what’s needed
(saves 40–70% extra data on mobile) 📱
sizes attribute → tells browser the intended display width at different breakpoints
width and height attributes → prevents layout shifts
(huge CLS win) ✅
loading="lazy" + decoding="async" → faster initial page load & better perceived performance 🚀
Most modern CDNs (Cloudflare Polish/Image Resizing, Imgix, Cloudinary…)
generate all these variants automatically — just upload one master image! ✨
