A summary of JPEG XL

JPEG XL is a fusion of Google's PIK format and Cloudinary's FUIF format. The JPEG XL Image Coding System contains a wide range of features that are especially suited for responsive web environments, so your content will look great on a variety of devices.

Compared to existing image formats, it will offer various advantages. It will be significantly smaller but will offer comparable quality. Decoding and encoding are fast and parallelizable, and progressive encoding is one of the features. Accordingly, it supports a wide gamut, higher resolutions, bit depths, and dynamic ranges, as well as lossless coding.

As an image with a maximum of a billion pixels on each side and up to 4100 channels, it is perfectly suited to store large amounts of information, whether it be synthetic or photographic. The JPEG XL format was designed to take advantage of multicore and SIMD, and actually decodes at a faster rate than JPEG.

By migrating to JPEG XL, storage costs can be reduced since servers can store just one JPEG XL file for both JPEG and JPEG XL clients. Lossless transcoding of existing JPEG files to JPEG XL significantly reduces their size. JPEG XL is unique in that it provides value to existing JPEG users and to new users alike. By using its coding tools, JPEG can be transmitted and stored at a 22% reduction in cost, while retaining exact byte-for-byte reconstruction of the original. The prevention of transcoding and additional artifacts contributes to the preservation of our digital heritage.

JPEG XL is also royalty-free patent software, in addition to being Free and Open Source Software (FOSS). You can easily convert multiple images to JXL with our converter. It supports conversion from JPEG to JPEG XL, PNG to JPEG XL, WebP to JPEG XL, and AVIF to JPEG XL. It is completely free, supports bulk conversion, and works client-side. Image files are not uploaded to the cloud.
