JPEGmini is a patent-pending photo recompression technology, which significantly reduces the size of photographs without affecting their perceptual quality. The technology works in the domain of baseline JPEG, resulting in files that are fully compatible with any browser, photo software or device that support the standard JPEG format.

JPEGmini is capable of reducing the file size of standard JPEG photos by up to 80% (5X), while the resulting photos are visually identical to the original photos. The JPEGmini algorithm imitates the perceptual qualities of the human visual system, ensuring that each photo is compressed to the maximum extent possible by removing redundancies, without creating any visual artifacts in the process. This enables fully automatic, maximal compression of photos with no human intervention required.

JPEGmini can be implemented in end-user devices such as cellular phones, cameras, and personal computers, to reduce storage requirements for photos, and reduce the time and bandwidth required for uploading the photos to online services. It can also be implemented in image-centric data centers, to reduce Total Cost of Ownership (TCO), including storage, bandwidth, electricity, and floor space.
