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 reduces the file size of your photos by up to 5X, while keeping their original resolution, quality and JPEG format. With JPEGmini you can optimize all your photos to free up valuable hard drive space, and share full-resolution photos with your friends much faster. JPEGmini supports personal photos with a resolution of 2 to 17 megapixels.
