What happens to the transparent background when converting PNG to JPG?

JPG does not support transparency, so transparent areas will be filled with white (or your chosen background color). To keep transparency, use PNG or WebP format.

What quality setting is best for PNG to JPG?

We recommend 85-90% as the best balance between file size and quality. For photos, 80% is almost indistinguishable; for high-fidelity images, use 95%.

How much smaller will the file be after conversion?

PNG to JPG at 85% quality usually reduces file size by 60%-80%. The exact amount depends on image content; colorful photos compress better.
