Which image format is especially suitable when an image needs transparent areas?
Correct!
PNG supports transparency through an alpha channel. This allows individual image areas to be fully or partly transparent, which is useful for logos, icons, and cutout graphics. PNG also uses lossless compression. The classic JPEG format, by contrast, is mainly used for photographs and does not provide a standard alpha channel for transparency.
