Frequently Asked Questions

QWill converting JPG to PNG improve quality?

No. PNG is lossless, but it cannot restore detail already lost to JPEG compression. It simply prevents further quality loss.

QDoes the PNG have a transparent background?

JPG files have no transparency, so the resulting PNG keeps the original solid background.
