Match the content
JPG or WebP works well for most photos. PNG or transparency-capable WebP suits logos and images requiring transparent pixels.
Converting an image re-encodes its data; simply changing a filename extension does not.
Watch for lost properties
JPG cannot preserve transparent areas. Converting an animated GIF to a still format may discard animation.
Compare the actual file size and visual result. A new extension does not guarantee a smaller file.
