It is lighter than different formats (when it does not show animations).
Disadvantages:
It handiest handles 256 hues and is therefore now not appropriate for showing images or drawings with gradients.
Example 3: this photograph in GIF layout, reveals a sturdy moire (particularly inside the sky and the combination of the diver) and a pixelization of the textual content.
Example 4: small animation Gif, displayed in a discounted length because the burden of this one could were too critical if one had stored the size of show of the alternative pictures.
