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
