Technical Specifications
Compression Methods
WebP employs Superior compression tactics to scale back file measurement even though retaining significant impression excellent. These tactics incorporate:
Predictive Coding: Much like the method Employed in VP8 movie encoding, predictive coding in WebP makes use of neighboring pixel values to predict the worth of a pixel. The encoder then only must store the distinction between the actual pixel benefit plus the predicted worth, which is typically scaled-down and calls for significantly less data.
Entropy Coding: WebP takes advantage of a combination of Huffman coding and LZ77, a lossless information compression algorithm, to competently encode the main difference values. This cuts down redundancy and optimizes the storage of impression information.
Shade Area Transformation: WebP visuals are usually encoded during the YUV colour House, which separates the luminance (brightness) and chrominance (colour) parts. This allows for more successful compression by prioritizing the luminance component, and that is more perceptually essential to human eyesight.
Lossy and Lossless Compression
WebP supports the two lossy and lossless compression:
