GIF does support animation, and is most used for small web animations.

Its also well suited for web, as the GIF format can be used online.

Suitable for line art such as logos which is good considering it uses lossless compression.

Not commonly used for digital photography, as it is limited to 256 colours.

GIF Stands for Graphical Interchange Format. GIF files are a format commonly used for graphics presented on websites. GIF's can contain a maximum of 256 colors, supports up to 8 bits per pixel and are therefore best for images that contain simple shapes, a limited color palette, text and other elements as opposed to photos.

GIF files have the file extension .gif. GIF files are compressed using "lossless" compression, meaning image quality is not sacrificed as file size reduces. However, if you save images with many colors as GIF files with a limited color palette, you will notice a reduction in quality. This is most obvious in photos. It uses the RGB colour space.

• Gatan Image Filter - The full name of the file format

Colours supported = 8bit colours (or 256 colours although it is possible to create a true colour image by splitting the gif image up into seperate gif images - each one containing up to 256 colours. an example of the 'True colour method is shown above)

Example of a GIF

To render a full-color image as a GIF, the original image must be broken down into smaller regions having no more than 255 or 256 different colors. Each of these regions is then stored as a separate image block with its own local palette and when the image blocks are displayed together (either by tiling or by layering partially transparent image blocks) the complete, full-color image appears. For example, breaking an image into tiles of 16 by 16 pixels (256 pixels in total) ensures that no tile has more than the local palette limit of 256 colors
