PNG to JPG Technical Details

PNG uses lossless compression and supports transparency. JPG uses lossy compression which discards some data to achieve smaller file sizes. When converting PNG to JPG, transparency is replaced with a white background. Quality slider controls compression level: 100 = minimal compression, 1 = maximum compression.

Questions fréquentes
