Sponsors

The libjpeg-turbo Project relies on donations and funded development opportunities in order to supply our enterprise-quality JPEG codec for free. If your organization has benefited from using libjpeg-turbo, then please consider sponsoring our project so that we can continue to provide this valuable service to your organization and others.

Sponsorship can take two forms. Project sponsors fund the development of specific features/fixes that they need. General sponsors donate money toward the libjpeg-turbo General Fund, which is used to pay for continued maintenance, integration of features/fixes submitted by the community, and hot projects that are not funded by project sponsors.

Organizations who donate to The libjpeg-turbo General Fund, purchase support, donate equipment, or otherwise sponsor the project at a level of US$1000 or greater can opt to have their logo displayed on this page. If you are interested in becoming a general sponsor, purchasing support, or in funding a specific feature/fix, then contact the project admin.

We also accept smaller donations to the libjpeg-turbo General Fund through GitHub Sponsors or PayPal. Every dollar received goes directly toward funding the labor necessary to develop and maintain libjpeg-turbo.
