Question 1

Why convert JPG to WebP?

Accepted Answer

WebP typically produces a noticeably smaller file than JPG at the same visual quality, which is why it's become the default recommendation for web performance audits (including Google's own PageSpeed Insights).

Question 2

Will WebP display everywhere?

Accepted Answer

Every browser in general use today supports WebP. The main reason to keep a JPG around is compatibility with older software outside the browser — for example some desktop image editors and design tools.

Question 3

Can I set a maximum file size for the WebP output?

Accepted Answer

Yes — turn on 'Maximum file size' and it's applied together with the format change in one pass.

Question 4

Does WebP support transparency like PNG?

Accepted Answer

Yes, unlike JPG. If your source has transparency and you convert from PNG rather than JPG, WebP keeps it.
