INDEPENDENT JPEG GROUP

IJG is an informal group that writes and distributes a widely used free library
for JPEG image compression. The first version was released on 7-Oct-1991.

The current version is release 9e of 16-Jan-2022. This is a stable and solid
foundation for many application's JPEG support.

You can find our original code and some supporting documentation in the
directory files. There is a Windows format package in zip archive format
jpegsr9e.zip and a Unix format package in tar.gz archive format
jpegsrc.v9e.tar.gz. A collection of modified versions with adaptions and error
fixes for system maintenance is available on jpegclub.org in the directory
support.

To learn more about how to use JPEG, see the JPEG FAQ. If you'd like to learn
about how JPEG works, start with the comp.compression FAQ.

IJG is not affiliated with the ISO/IEC JTC1/SC29/WG1 standards committee
(previously known as JPEG, together with ITU-T SG16).

IJG development continues. Advanced features are being prepared for coming
releases...

Version 9f is currently in development and is planned for release in January
2024.
The development site for new versions is the JPEG Reference site.
