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 was developed by ICVT, which is dedicated to optimizing media compression technologies. ICVT’s goal is to improve the user experience and reduce the costs associated with storing and transmitting media files.
