Huffman & Shannon–Fano Codes
Build prefix codes from character frequencies and inspect encoded bits.
Processing stays in your browser. Counts Unicode code points. Reports theoretical payload bits; codebook/storage overhead is excluded. Output is a teaching report, not a compressed archive.
How to use the huffman & shannon–fano codes
Build prefix codes from character frequencies and inspect encoded bits. Complete the text (up to 10000 characters), coding algorithm fields above, or upload a UTF-8 text file for text (up to 10000 characters). Choose Run tool, review the output, then copy or download the result.
Example
Huffman assigns frequent characters shorter codes.
