JPEGmini thumbnail

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 Beamr, an imaging technology company that powers some of the world's top web publishers, social networks and media companies. Beamr's goal is to improve the user experience and reduce the costs associated with storing and transmitting media files but for 3D artists, smaller image sizes may also be an important factor.

JPEGmini comes in several flavours: as a desktop application for both Windows and Mac and as a server application. The desktop apps have a free version with full functionality - the only limitation is comressing 20 images a day. Completely enough to evaluate the software as well as for hobbyists or occasional bloggers (who wish to opőtimize their images for the web for instance). I have tried the Windows version and was blown away by the quality despite the reduction in file size. Maybe an option to remove EXIF data, too, would be a nice addition - now I needed to do this in another step in Gimp.

The server version has a 30-day trial and I have not tried it (yet)
