Data Compression Ratio Analyzer
Overview
The Data Compression Ratio Analyzer compares different compression algorithms and computes compression ratios. Test run-length encoding, LZ77, Huffman, and arithmetic coding on various data types. See which algorithms work best for different data patterns.
Tips
- Compression ratio = original size / compressed size (higher is better)
- Run-length encoding: good for repeated values
- LZ77: dictionary-based, finds repeated sequences
- Huffman: optimal prefix codes for known frequencies
- Arithmetic coding: better than Huffman, encodes entire message
- Different algorithms suit different data types
- Text compresses better than random data
- Entropy sets lower bound on compression
