Will the WebP file have transparency?

Not automatically — JPG images carry no alpha channel, so the converted file is fully opaque. The difference is that WebP can store transparency, so after converting you can open the image in an editor and erase the background without another format change.

Will quality drop when re-encoding JPG as WebP?

Slightly, in principle. JPG and WebP are both lossy formats, and every re-encode discards a little more data — the digital equivalent of photocopying a photocopy. In practice, keeping the quality slider high makes the difference imperceptible. Just avoid converting the same image back and forth repeatedly.

Where can WebP files be used?

Every modern browser — Chrome, Firefox, Edge, and Safari 14 or later — displays WebP natively, and current versions of major image editors open it too. Only quite old software may struggle, which is one reason to keep your original file as a fallback.

How much smaller will the WebP file be?

Photographic JPGs usually come out noticeably smaller at comparable visual quality — enough to noticeably speed up image-heavy pages.
