Build a Huffman tree from any text and watch the merges that produce it.
Free Huffman Encoding Visualizer
Huffman coding is one of the clearest examples of a greedy algorithm โ but the tree-building process is hard to follow from a textbook diagram alone. Our free Huffman coding calculator builds the tree from any text you enter and lists every merge step, so you can watch the two lowest-frequency nodes combine again and again until a single tree remains.
Once built, the tool derives each character's binary code from the tree and shows the fully encoded bitstring, alongside a direct comparison to fixed-length encoding โ so you can see exactly how much space Huffman coding saves. Decode the bitstring back to the original text to verify the code table works both ways.
Built for computer science and data structures students studying greedy algorithms and compression. No sign-up, no downloads.
