GIF is a lossless compression introduced by CompuServe in 1987 using Lempel-Ziv-Welch (LZW) lossless data compression.

Lossless. Compression techniques do not remove detail from the image.
Lossy= You lose somedata Lossless= You dont
The most common file extensions for image files are: GIF: Old, can be animated, 8-bit color JPEG/JPG: High compression rate, No transparency, lossy PNG: Can be transparent, lossless
Pict files can use 2 different forms of compression. 1- RLE Compression (the default) is lossless. 2- JPEG compression (only on some systems/graphics programmes) is lossy.
The Graphic Interchange Format (GIF) is a lossless image format, meaning it preserves the original image data without any loss in quality when compressed. However, it supports a limited color palette of up to 256 colors, which can lead to a reduction in image fidelity for more complex images. This characteristic makes GIF suitable for simple graphics, animations, and images with solid colors, but not ideal for detailed photographs.
