The Preliminary launch of WebP supported only lossy compression. However, in November 2011, Google introduced assist for lossless compression and transparency (alpha channel), earning WebP a versatile format capable of handling a wide range of image kinds.
Technical Specifications
Compression Methods
WebP employs Superior compression tactics to lower file sizing whilst preserving substantial impression excellent. These procedures include:
Predictive Coding: Similar to the method Employed in VP8 movie encoding, predictive coding in WebP works by using neighboring pixel values to predict the value of the pixel. The encoder then only should retail outlet the distinction between the actual pixel value and also the predicted value, which is often scaled-down and involves considerably less knowledge.
Entropy Coding: WebP employs a combination of Huffman coding and LZ77, a lossless data compression algorithm, to competently encode the primary difference values. This lowers redundancy and optimizes the storage of picture facts.
Colour House Transformation: WebP photos are generally encoded while in the YUV coloration Room, which separates the luminance (brightness) and chrominance (color) factors. This enables For additional successful compression by prioritizing the luminance component, which happens to be additional perceptually vital that you human eyesight.
Lossy and Lossless Compression
WebP supports equally lossy and lossless compression:
Lossy Compression: WebP's lossy compression utilizes the approaches pointed out above to appreciably lower file size although preserving impression quality. This makes it ideal for Website use, in which speedy loading instances are very important.
