The standalone libwebp library serves as a reference It can also use a local palette if noĪ WebP file consists of VP8 or VP8L image data, and a containerīased on RIFF. Lossless WebP compression uses already seen image fragments in order toĮxactly reconstruct new pixels. In a block, and then encodes only the difference. PredictiveĬoding uses the values in neighboring blocks of pixels to predict the values Method used by the VP8 video codec to compress keyframes in videos. Lossy WebP compression uses predictive coding to encode an image, the same Which can provide reduced sizes compared to GIF and APNG. Lossy, lossless and transparency are all supported in animated WebP images, Is acceptable, lossy WebP also supports transparency, typically providing Lossless WebP supports transparency (also known as alpha channel) at aĬost of just 22% additional bytes. Lossy images are 25-34% smaller than comparable JPEG images at equivalent WebP lossless images are 26% smaller in size compared to PNGs. Using WebP, webmasters and webĭevelopers can create smaller, richer images that make the web faster.

Image files that employ JPG compression are commonly called "JPG files" and are stored in variants of the JIF image format.
Google has proposed using WebP for animated images as an alternative to the popular GIF format, citing the advantages of 24-bit color with transparency, combining frames with lossy and lossless compression in the same animation, and support for support seeking specific frames. JPG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
JPG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. WebP-related software is released under a BSD license. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP is an image format employing both lossy and lossless compression.
