Why does the background turn black when I convert PNG to JPG?

JPG has no transparency, so transparent areas are filled with a solid colour. Export to PNG or WebP to keep a transparent background.

Which format should I pick?

WebP or JPG suits photographs; PNG suits logos, icons and flat-colour images, or anything that needs transparency.
