Head to head
WebP vs JPG (JPEG)
WebP and JPG are both used to compress photographic images, but WebP is the modern successor. WebP produces files roughly 25-35% smaller than JPG at the same visual quality, and unlike JPG it supports transparency and animation. JPG remains universally compatible with every device, editor, and platform ever made, which is why it is still the safe default for email attachments and legacy systems.
