Usually a fifth of the size, for photographs.

When this is a good idea
For photographs, JPEG at quality 85 is typically 70 to 90% smaller than the same picture as PNG, with no visible difference. For screenshots of text, interfaces and diagrams, it is the wrong move. JPEG smears sharp edges and coloured text, and the file often is not much smaller anyway. Keep those as PNG, or use WebP.
Transparency
JPEG has no alpha channel. Transparent areas are composited onto white by default here. Untick the option to get black instead.
Common questions
What quality should I use?
85 is the standard sweet spot. Below 70 the artefacts around edges start to show.
Can I go back to PNG afterwards?
You can convert it back, but the JPEG compression is permanent. Keep the PNG if you might edit the image again.
