The modern web has moved far beyond legacy GIF, JPEG, and PNG. Today, three advanced codecs compete for dominance.
WebP (Google)
Supported by >97% of global web browsers. Provides 25%–35% smaller file sizes than JPEG with full alpha transparency support.
AVIF (Alliance for Open Media)
Based on the royalty-free AV1 video codec. Offers 50% smaller sizes than JPEG and superior highlight preservation over WebP. Now supported by all major browsers.
HEIC (MPEG / Apple)
Dominates iOS hardware capture due to dedicated Apple silicon acceleration, but royalty licensing prevents it from becoming a native web standard.
