GIF images use the following compression techniques:

☛ - Lossless Compression: Statistical redundancy is exploited for representing data in more concise manner.

☛ - Real-world data consists of statistical redundancy.

☛ - Lampel-Ziv Compression: One of the most popular algorithms.

☛ - Compression process is slow.

☛ - It implements table-based compression, in which the table entries are substituted to repeat the strings of data.

☛ - The table is encoded using Huffman encoding.
