These replacements, in turn, are often termed "GIFs" despite having no relation to the original file format. While once in widespread usage on the World Wide Web due to its wide support and portability between applications and operating systems, usage of the format has declined for space and quality reasons, often being replaced with video formats such as the MP4 file format. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients but well-suited for simpler images such as graphics or logos with solid areas of color. It also supports animations and allows a separate palette of up to 256 colors for each frame. The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. The Graphics Interchange Format ( GIF / ɡ ɪ f/ GHIF or / dʒ ɪ f/ JIF, see pronunciation) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987.
