Modern Formats
WebP offers 25-35% smaller files than JPEG at similar quality. AVIF can achieve even better compression (50%+) but has limited browser support.
Quality Tips
For photos: 80-85% quality is usually optimal. For graphics/text: use PNG or WebP lossless. For thumbnails: 70% quality is sufficient.
