WebbIn the field of data compression, Shannon–Fano coding, named after Claude Shannon and Robert Fano, is a technique for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured). It is suboptimal in the sense that it does not achieve the lowest possible expected code word length like Huffman coding.

Similar to Huffman coding the Shannon Fano algorithm used to create a uniquely decodable code. It was developed earlier than the Huffman coding algorithm by Claude Shannon and Robert Fano in the year of 1949. This technique also uses the probabilities of the data to encode it.
