Short answer
A JPG can be converted to WebP in a browser without uploading it. WebP typically produces a file 25-35% smaller than a JPEG of the same visual quality, because it uses a more modern compression method for the same kind of content. For a page carrying several photographs, that is one of the cheapest performance improvements available.

JPEG has been the default photographic format since the early 1990s and is still perfectly good, but the compression research did not stop there. WebP encodes the same photograph with roughly a third less data for the same perceived quality, and every browser in current use can decode it.
One thing to be careful about: converting a JPEG to WebP is a second lossy generation, and the artefacts of the first encode are now part of the picture being compressed. Always convert from the best original you have rather than from a copy that has already been through a messaging app.

Frequently asked questions
How much smaller is a WebP than a JPEG?
Roughly 25-35% at the same visual quality. The gain is larger on smooth content such as skies and skin, and smaller on very detailed textures.
Will I see the quality drop?
At the Balanced setting, generally not, provided you start from a good original. Compare them side by side at full size if the image matters.
Should I keep the JPEG as a fallback?
It is rarely necessary for browsers now. It is still worth keeping the original for anything outside a browser — email clients, older desktop software and print workflows are much less consistent about WebP.
Can I convert back later?
Yes, with the WebP to JPG tool, though it is a third lossy generation. Keep the original JPEG if you may need it.
