About

  • Performs Lossless compression and decompression of .txt files using Huffman Coding technique .
  • Each character is assigned a unique variable length binary code, instead of its 8-bit representation, with more frequent characters having smaller codes. A Huffman Tree is created and stored to generate and decode these codes.
  • Compression ratio usually improves as the file size increases.
  • The website is made responsive (with HTML and CSS ) and interactive (with JavaScript ) .
  • An Info page is added to give more information about Huffman coding.
