JPEGmini is a photo compression tool developed by Beamr Imaging Ltd released in 2012 for Mac and Windows. It designed to reduce the file size of images and videos with limited quality reduction. [ 1 ] [ 2 ] [ 3 ]
Guetzli supports only the top of JPEG's quality range (quantizer settings 84–100) [7] [8] and supports only sequential (non-"progressive") encoding. Guetzli is more effective with bigger files. [8] Google says it is a demonstration of the potential of psychovisual optimizations, intended to motivate further research into future JPEG encoders. [2]
JPEG XR is an image file format that offers several key improvements over JPEG, including: [18] Better compression JPEG XR file format supports higher compression ratios in comparison to JPEG for encoding an image with equivalent quality. Lossless compression JPEG XR also supports lossless compression. The signal processing steps in JPEG XR are ...
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.
libjpeg is a free library with functions for handling the JPEG image data format. It implements a JPEG codec (encoding and decoding) alongside various utilities for handling JPEG data. It is written in C and distributed as free software together with its source code under the terms of a custom permissive ( BSD -like) free software license ...
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.
