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.
The .jpg filename extension refers to digital photography files or digital images that are associated with the JPEG file format specification. The joint photographic experts group, or JPEG for short, is a file format from the 'lossy image' class of image formats. Many devices including smartphones with inbuilt cameras and professional digital SLR cameras support the JPEG/Exif file format natively. Such support allow images captured on these devices to be stored directly into the jpg format without conversion. Efforts towards standardization of the JPEG format first begun in 1992 with ISO/IEC 10918-1:1994
FreeFileConvert uses tuned encoding for WEBP to JPG 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 JPG 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 JPG 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.
Being a 'lossy image' file format, digital image files saved as .jpg files use encoding algorithms that make inexact approximations of the photographic data to save on storage space during compression. This allows for relatively small files that are suited for delivery over networks or in low bandwidth scenarios. The jpg file format is flexible in that it accommodates a tradeoff between the size of the file and the image quality during compression. Image compression may leave noticeable artifacts in the produced image. The maximum resolution supported by the JPEG format is 4 Giga pixels.
