WebHuffman encoding algorithm is a data compression algorithm. It is a common type of entropy encoder that encodes fixed-length data objects into variable-length codes. Its purpose is to find the most efficient code possible for a block of data, which reduces the need for padding or other methods used to pad fixed-length codes with zeroes.
