WebP is a popular image format that has been developed by Google in 2010. The WebP technology deploys features of both the lossy and the lossless compression techniques that are totally in contrast to each other. The lossy compression technique is an irreversible data compression whereas lossless compression technique involves reversible data compression. However, the lossy compression technique is very useful in significantly reducing the file size for easy transfer and handling as well as to save on storage space. Compared to other image formats like JPEG and PNG, the WebP image formats retain the high quality despite allowing for nearly 34% more compression. This technology is useful as a large number of images can be viewed one after the other across the world at very high speed. There is a standalone library called libwebp in the GIT Repository that can be used as a reference for implementation of the WebP specifications. This library provides the necessary commands for encoding and decoding.
CMX stands for Corel Metafile Exchange Image File, it was a proprietary file format designed and used by the famous software company Corel Corporation. The CMX extension was used mostly in Corel's vector editing program, CorelDRAW or their image editing software CorelPaint. The CMX file not only contained the image but the data within the image which allowed stored information to be communicated between different software that could read that information.
FreeFileConvert uses tuned encoding for WEBP to CMX conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload WEBP files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized CMX results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent CMX audio with dependable progress tracking.
The algorithm for lossy compression technique in WebP images is based on the structure found in the VP8 video format which uses the intra-frame coding mechanism. The RIFF (Resource Interchange File Format) is used as the container format for these files. The lossless compression of WebP comprises of advanced compression techniques like using dedicated codes to entropy channels of different colors. This technique exploits the 2D or the 2 Dimensional localities for referencing distances in a backward order and maintains a color cache that has all the colors that have been used recently. It comprises of complementary basic techniques like Color Indexing Transformation, Huffman coding and Dictionary coding. There is almost a 19% to 64% reduction in image size depending on the source image format and whether the image is being converted to a lossy or a lossless format in WebP.
