Ever wondered which image format actually saves bandwidth without sacrificing quality? Let's break it down.
PNG is your reliable friend—lossless, great for graphics, but bloated for photos. WebP cuts file sizes by 25-35% and supports transparency. AVIF is the newcomer crushing it with 50%+ smaller files than PNG, but browser support isn't universal yet.
The real win? Use WebP for most cases—solid browser support and size savings. AVIF when you can afford a fallback. PNG for simple graphics or when you need maximum compatibility.
Pro tip: automate this with tools that handle format conversion and serve the right file to the right browser. Your users (and hosting bill) will thank you.
