JPG on the left, WEBP on the right

The same photo at the same quality, saved both ways. Drag the handle: they look identical, but the WEBP is the smaller file.

Here WEBP came out about 17 percent smaller, because this source was already a compressed JPG. On a clean original, Google's 25 to 34 percent figure is closer to what you will see. Either way the screen image is the same.

Why WEBP

What you actually gain

Smaller files

25 to 34 percent under JPG at the same quality, which is the single biggest lever for page weight.

Better Core Web Vitals

One format, both jobs

WEBP does small photos like JPG and transparency like PNG, so it can replace either on the web.
