When you rotate a JPEG photo, most image editors decode the photo, rotate the bitmap and then reencode it back to JPEG. This process slightly decreases the final image quality. Unlike other tools, the JPEG Lossless Rotator does not recode your photo but performs a special lossless block transformation. As a result, the rotated photo has exactly the same quality as the original. JPEG Lossless Rotator is easy to use and free utility.
