- Good for illustration, line art and flat areas of color.
- GIF compression is 8-bit and has a maximum of 256 colors.
- You can reduce the number of colors in a GIF image and choose options
to control the way colors dither in the application or in a browser.
- GIF format lets you create interlacing, and animations.
- GIF supports background transparency and background matting, in which
you blend the edges of the image with a Web page background color.

- Good for photographs and gradients.
- JPEG compression is 24-bit, which means files can contain up to 16.7
million colors.
- Unlike GIFs, the standard JPEG file is not interlaced (a problem addressed
by the Progressive JPEG).
- Preserves the broad range and subtle variations in brightness and
hue found in photographs and other continuous-toned images.
- The JPEG format does not support transparency.
- Artifacts, such as wave-like patterns or blocky areas of banding,
are created each time you save an image in JPEG format.
