JPG files are typically 50-80% smaller than PNG for photographic images. A 5MB PNG photo becomes a 1MB JPG with minimal visible difference.
Smaller JPG files load faster on websites and fit within email attachment limits. For photos (not graphics), JPG is the better web format.
Keep PNG if you need transparency, have text/graphics with sharp edges, or need lossless quality. JPG doesn't support transparency and can blur sharp edges.
JPG doesn't support transparency. Transparent areas in your PNG will become white (or another background color you choose) in the JPG output.
JPG is lossy, so some quality is lost. At 85-95%, the difference is imperceptible for photos. For graphics and text, PNG is better.
