Saving in JPEG format
Joint Photographic Experts Group (JPEG) format
is commonly used to save photographs and other
continuous-tone images. JPEG format retains all
color information in an image but compresses file
size by selectively discarding data. You can choose
what level of compression you want. A higher level
of compression results in lower image quality and
a smaller file size; a lower level of compression
results in better image quality and a larger file size.
