Why Convert JPEG to WEBP?
People convert JPEG to WebP to switch from lossy JPEG to lossless WebP to preserve full image quality, and to gain transparency support that JPEG lacks, and to add animation capabilities available in WebP, and to replace the 1992 JPEG standard with the modern WebP (introduced 2010), and to reduce file size significantly for faster web loading.
Lossless WEBP is the right choice whenever you plan to edit the image further or need pixel-perfect quality for UI assets, icons, or print. Unlike JPEG, saving WEBP multiple times introduces no additional quality loss.
