Why convert JPG to WebP rather than JPG?

WebP lands 25-35% smaller than JPG at the same visual quality and keeps transparency, which JPG cannot do at all. Every browser in current use renders it. JPG is still the safer pick if the image has to survive email clients or very old software.

Does converting JPG to WebP lose quality?

Both JPG and WebP are lossy, so re-encoding adds a small amount of generational loss. At quality 80 and above it is invisible at normal viewing sizes. Convert from the best source you have rather than from an already-compressed copy.

How much bigger or smaller will the WebP file be?

Smaller, usually dramatically so — JPG files are 25-35% larger than a WebP of the same visual quality. The exact saving depends on the image, but photographic content at quality 80-85 commonly lands at a third of the original.

Will transparency survive the conversion?

WebP supports transparency, but JPG has none to carry over, so the result is fully opaque. You can add an alpha channel afterwards in an image editor.
