Converter webp to gif2/8/2024 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.

When lower values are used, more frames will be converted to key frames. These two options are relevant only for animated images with large number Lossless compression and kmin = 3, kmax = 5 for lossy compression. Default values are kmin = 9, kmax = 17 for Taken into account in both these special cases. Of 1 will result in all frames being key frames. Insert some key frames into the output animation as needed so that thisĪ kmax value of 0 will turn off insertion of key frames. (independently decodable frames) in the output animation. Specify the minimum and maximum distance between consecutive key frames Result in faster processing time at the expense of larger file size and Values are used, the encoder will spend more time inspecting additionalĮncoding possibilities and decide on the quality gain. Off between encoding speed and the compressed file size and quality. m int Specify the compression method to use. Uses lossless compression by default, but can be combined with -q, -m, Picks the dispose method resulting in the smallest output for each frame. min_size Encode image to achieve smallest size. Best quality is achieved by using a value In case of lossyĬompression (specified by the -lossy option), a small factor produces a MaximumĬompression is achieved by using a value of 100. In case of lossless compression (default), a small factorĮnables faster compression speed, but produces a larger file. q float Specify the compression factor for RGB channels between 0 and 100. mixed Mixed compression mode: optimize compression of the image by pickingĮither lossy or lossless compression for each frame heuristically. lossy Encode the image using lossy compression. h, -help Usage information -version Print the version number (as ) and exit. The data will be read from 'stdin' instead of a file. This option must appear last.Īny other options afterward will be ignored. This option is useful if the inputįile starts with an "-" for instance. string Explicitly specify the input file. Using "-" as output name will direct output to 'stdout'. Perform conversion but only report statistics. The basic options are: -o string Specify the name of the output WebP file. Gif2webp converts a GIF image to a WebP image.
