GIF, Graphic Interchange Format or Bitmap (CompuServe) is a file extension for an often animated raster graphics file and is the second most common image format used on the World Wide Web after JPEG. The GIF 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. It also supports animations and allows a separate palette of up to 256 colors for each frame.
These palette limitations make the GIF format less suitable for reproducing color photographs and other images with continuous color, but it is well suited for simpler images such as graphics or logos with solid areas of color. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. But some time due to unavoidable reasons that may lead to loss of GIF files that requires the need for gif recovery if there is no backup available….
