What are TIFs, GIFs, and JPEGs?

TIF or TIFF (Tag Image File Format)

GIF (Graphics Interchange Format)

JPEG (Joint Photographic Experts Group)
TIFF files are commonly used to incorporate images into documents for desktop publishing. Tiffs are convenient because they may be viewed by numerous image viewing applications. Tiffs are uncompressed images that contain more computer information than gifs or jpegs and therefore usually reproduce better for print than gif files.

 

Gifs are usually better for reproducing logos or drawings.GIF files support a maximum of 256 colors, which makes them practical for almost all graphics except photographs. The GIF format supports transparency and is compressed. Gifs can be animated.

Jpegs are usually better for reproducing photographs. The JPEG format, with its support for 16.7 million colors, is primarily intended for photographic images, particularly for use on the web since the files are compressed and download quickly. Jpegs cannot be animated
