Lower makes a smaller file.
A PNG keeps every pixel exactly, which is why screenshots and exported drawings arrive so large. A JPG throws away detail that an eye does not notice, and a photograph or a screenshot of a photograph often comes out five or ten times smaller. Mail systems and older upload forms also accept JPG everywhere, which is not true of newer formats.
A JPG cannot hold a clear background. Anything transparent in the PNG turns solid, and this tool fills it with black. A JPG also loses a little more each time it is saved, so keep the PNG if you plan to edit the picture again.
Do not use JPG for a logo, a diagram, or a screenshot of text. Sharp edges pick up a grey fuzz that gets worse at lower quality. Convert those to WebP instead, which stays sharp and is still much smaller than PNG.
