Understanding WebP Technology
Advanced Compression Techniques
WebP uses Google's VP8 compression algorithm, which employs predictive coding to achieve superior compression. Unlike JPEG's block-based compression, WebP predicts pixel values based on surrounding blocks, dramatically reducing file sizes.
- • Block Prediction: Smart algorithms predict image content
- • Adaptive Quantization: Different compression for different image areas
- • Entropy Encoding: Optimized data representation
- • Color Space Optimization: Efficient handling of chrominance data
