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.
