The short version
JPG, PNG, WebP, AVIF, GIF, SVG, HEIC — picking the wrong image format costs bandwidth, quality, or compatibility. Picking the right one makes pages faster, images crisper, and files smaller without anyone noticing. The rules aren’t intuitive (JPG isn’t always smaller than PNG; WebP isn’t always better than JPG), and the landscape shifted in the last few years with AVIF rolling out at scale. This guide maps each format to its best use, explains the compression tradeoffs that matter, covers transparency and animation support, browser compatibility in 2026, and the modern workflow for serving the right format to every user.
Lossy vs lossless — the core tradeoff
GIF is 256-color only, horrendous compression compared to modern formats, and its only remaining advantage is universal support.
JPG deep dive
Reach for GIF only if you’re embedding in old email clients or legacy docs.
PNG deep dive
Apple’s default photo format since iOS 11 (2017). Excellent compression — files half the size of equivalent JPG.
SVG deep dive
Serve the best format each browser supports:
WebP deep dive
Browser tries AVIF → WebP → JPG, picks the first it supports. Zero-cost progressive enhancement.
AVIF deep dive
Modern CDNs (Cloudflare Images, Vercel, Netlify, imgix, Imagekit) auto-convert on request. Upload a JPG; CDN serves AVIF to Chrome, WebP to Safari 14, JPG to older browsers. Resize on the fly from URL parameters.
GIF — legacy for a reason
For any site with > 100 images, a CDN with image optimization is usually worth the cost.
