Clear answers about image formatting, compression standards, and privacy.
Why do transparent PNGs turn black when converted to JPG on some tools?
JPEG does not support transparency. When an alpha channel is discarded without proper blending, transparent pixels default to black. Our engine blends transparent regions against your chosen solid color (like pure white) with anti-aliased edge smoothing.
