Certain images (practically anything but photos) look and work better as PNG. These generally include flags, graphics, icons, diagrams and certain screenshots (such as from old video or arcade games.)
PNG photos that should be JPEGPNG is not an efficient format for photographs. These should be converted to JPEG to save space.
Pictures that need to be retouched, trimmed and scaledThese include images with captions that are too small to read or photos that contain irrelevant surroundings.
