Huffman coding animated on your own text: merge the two rarest symbols until one tree remains, read off the prefix codes, and see the compression ratio.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Huffman Coding Visualizer is a free, browser-based tool that helps you tidy up and standardize messy datasets. Huffman coding animated on your own text: merge the two rarest symbols until one tree remains, read off the prefix codes, and see the compression ratio. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Clean obvious quality problems before analysis, imports, dashboards, or automation.
Review the preview, copy or download the result, and keep everything local in your browser.
Activity Selection Visualizer: The classic greedy scheduling problem animated: sort by finish time, sweep, and select every compatible activity — with the exchange-argument intuition.
Open toolAlgorithm Academy: 35+ classic algorithms animated step by step — searching, counting/radix/bucket sort, dynamic programming tables, greedy, backtracking, KMP, graph algorithms, max flow, and convex hull — with auto-play, next/prev stepping, adjustable interval, and pseudocode that highlights the running line.
Open toolData Structure Playground: Hands-on stack, queue, linked list, and hash table — every push, pop, pointer rewire, and collision narrated with its O(1)/O(n) cost, plus an interactive Big-O growth explorer.
Open tool1Huffman coding for "ABABDABACDABABCABAB". Frequencies: A=8, B=7, D=2, C=2. GREEDY KEY: repeatedly merge the two RAREST symbols — rare symbols end up deep (long codes), common ones shallow (short codes).

Optimal prefix-free codes: merge the two rarest symbols until one tree remains. ZIP/JPEG/MP3 all descend from this.
