JPEG XL is a royalty-free open standard for the compressed representation of raster graphics images. It defines a graphics file format and the abstract device for coding JPEG XL bitstreams.

The JPEG XS standard is a classical wavelet-based still-image codec without any frame buffer. While the standard [27] defines JPEG XS based on a hypothetical reference coder, JPEG XS is easier to explain through the steps a typical encoder performs: [28]
Typically, compressions using lossless operation mode can achieve around 2:1 compression ratio for color images. [5] This mode is quite popular in the medical imaging field, and defined as an option in DNG standard, but otherwise it is not very widely used because of complexity of doing arithmetics on 10, 12, or 14bpp values on typical embedded 32-bit processor and a little resulting gain in ...
JPEG 2000, an improvement intended to replace JPEG by the JPEG committee as of 2000 JPEG XS , format for image and video with very low latency, more efficient for streaming high quality video JPEG XL , is a royalty-free raster-graphics file format that supports both lossy and lossless compression.
JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group.It is suitable for both lossless and lossy compression. . According to a press release [1] from the Group, in its lossless mode JBIG2 typically generates files 3–5 times smaller than Fax Group 4 and 2–4 times smaller than JBIG, the previous bi-level compression standard released by
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
JPEG XL (ISO/IEC 18181) was published in 2021–2022. It replaces the JPEG format with a new DCT-based royalty-free format and allows efficient transcoding as a storage option for traditional JPEG images. [80] The new format is designed to exceed the still image compression performance shown by HEIF HM, Daala and WebP.
