JPG vs WebP
WebP was designed as a replacement for both JPG and PNG on the web. For most photographic content it produces smaller files at comparable quality.

File size
In practice, WebP lossy encoding tends to produce meaningfully smaller files than JPG for the same perceived quality. The exact saving depends heavily on the image — smooth content benefits most, heavily textured content least.
Features
WebP supports transparency and animation; JPG supports neither. That means one WebP file can replace a JPG photo, a PNG logo or a GIF loop.
Support
Every current major browser decodes WebP. Outside the browser, support is patchier: some older desktop applications, some email clients and some upload forms still expect JPG or PNG.
