Frequently Asked Questions

What happens to transparency when converting PNG to JPG?
Because the JPEG standard does not support alpha transparency channels, our converter fills transparent areas with a clean solid white background so your image looks natural and clear.
Are converted files identical in quality to original files?
Converting to PNG is completely lossless. When converting to JPEG or WebP, you can use our Encoding Quality slider (set to 90% or higher) to ensure indistinguishable visual fidelity.
