This online calculator generates Huffman coding based on a set of symbols and their probabilities. A brief description of Huffman coding is below the calculator.

The calculators encode string to base64 string and decode back to original string. Special characters (+/) , generally produced by base64 algorithm, can be replaced by the data provided in additional parameter.
