Why Convert JPG to AVIF?
People convert JPEG to AVIF to switch from lossy JPEG to lossless AVIF to preserve full image quality, and to gain transparency support that JPEG lacks, and to add animation capabilities available in AVIF, and to replace the 1992 JPEG standard with the modern AVIF (introduced 2019), and to reduce file size significantly for faster web loading.
Lossless AVIF is the right choice whenever you plan to edit the image further or need pixel-perfect quality for UI assets, icons, or print. Unlike JPG, saving AVIF multiple times introduces no additional quality loss.
