libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.
libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and VirtualGL projects made numerous enhancements to the codec in 2009, and in early 2010, libjpeg-turbo spun off into an independent project, with the goal of making high-speed JPEG compression/decompression technology available to a broader range of users and developers.

Note from the project maintainer: libjpeg-turbo is in desperate need of a general sponsor, a company or organization who is willing to fund a certain number of hours every year to pay for project maintenance, integrating features and fixes from the community, and other projects that are necessary for the continued health of libjpeg-turbo. Please see this article for more details.
If you have benefited from this product, then we also appreciate individual donations (click on the link below.) Every dollar helps to ensure that I can continue to provide this enterprise-quality, high-performance software free of charge and in a vendor-neutral manner. Alternately, if you have any improvements in mind for the product, please consider sponsoring my labor to implement them.
