Image Compression Techniques

JPEG - finds redundancies in files to compress data - reduces sections of images to blocks of pixels - de facto standard of images on the internet
PNG - Portable Network Graphics - its compression process is entirely lossless; meaning that the compressed file can reconstruct the source image exactly - supports transparency
GIF - Graphics Interchange Format - allows 8-bit per pixel - allows upto 256 colours per pixel - supports animations
