What's the difference between JPEG, PNG, WebP, and AVIF?

JPEG is best for photos with many colors but doesn't support transparency. PNG is ideal for graphics with transparency but larger file sizes. WebP offers better compression than JPEG with transparency support. AVIF provides the best compression and quality but has limited browser support. Choose based on your specific needs and target audience.

How much can I reduce my image file sizes?
