![]() In addition to static images, WebP also supports animation, allowing you to create moving images with a smaller file size than other animated image formats like GIF. WebP is a relatively new image format developed by Google that provides lossy and lossless compression for images on the web. If no interesting match is found, it can make use of the local Palette. Predictive coding puts to use the values in nearby blocks of pixels to tell the values in the block and then creates only the difference. WebP compression makes use of predictive coding to create images. Yet also, WebP Lossy images are smaller than JPEG images with 25-30% and an equivalent SSIM quality index respectively. In comparing webP lossless to PNGs in size the former is 26% smaller. Using web, webP, and webmaster, developers can make smaller, optimized images to improve the website speed. The WEBP format is a new image format that offers improved lossy and lossless image compression for the web. The limitations in color are up to 256 for a particular frame and are likely not suitable for photographs with color gradients and reproducing other images. But for an animated GIF, there are combinations of different frames and images into a file and displayed in packets to bring about a short video or an animated clip. A specific image GIF carries up to 8bits per pixel and roughly 246 colors can fit across the image, compared to a JPEG which can carry up to 16million colors and contrast the eyes.Īt the advent of the internet, GIFs were a number one choice due to their compatibility and a low requirement on the bandwidth of graphics which occupies a solid area of color. The GIF uses a compression algorithm of the LZW compression to optimize image quality. It is a highly compressed type of image and a property of Unisys. GIF is derived from each first later of the words Graphical Interchange Format. In the following paragraphs you find more details about the two formats: Another difference is the compression which can be lossless and lossy for WebP but only lossless for GIF. The main difference is the color depth: While the WebP format supports 24-bit RGB color with an additional 8-bit alpha channel, GIF only offers 8-bit color depth and a 1-bit alpha channel. However, the first isn't as widely supported as other image types and so certain devices and programs, including Apple’s Safari browser, are unable to open them.The WEBP and GIF image formats in comparison:īoth WebP and GIF are image file formats to serve images in the world-wide-web. WEBP files can be opened using various applications, including GIMP, Adobe Photoshop, Apple Preview, Microsoft Paint, Google Chrome, Opera, Microsoft Edge, and Mozilla Firefox. Due to these benefits, the format is often used for web graphics, and digital photography. The advantages of using WEBP include smaller file sizes, lossless compression, transparency support and animation support. This raster image format was designed to enable users to load images more quickly with a lower storage footprint, while retaining a higher quality or resolution than more traditional image formats such as JPG. The WEBP file format was originally developed by On2 Technologies, and then further developed by Google after they acquired the company in 2010. Many film and TV companies produce and publish their own GIFs as part of their viral marketing strategies. GIFs are big business and they’re widely used by advertisers and marketeers. Billions of animated GIFs are now sent between users or posted online every day. They were mostly replaced by JPG and PNG until they were integrated into messaging and social media apps and started being used for memes. GIFs are often used on websites for animated objects and navigation buttons, and on social media to share video clips and animated images. To make GIFs easier to share, the image or animation is compressed with lossless compression, creating a smaller file size without noticeably affecting image quality. GIFs are raster images made up of pixels and containing up to 256 colours. They will open in almost all image programs and on almost all devices. Although traditionally still images, GIFs can also include short bursts of soundless animation. GIF stands for Graphical Interchange Format.
