JPEG Lossless Rotation
All people usually make photos with different shot orientatons, and some photos need to be rotated. When you rotate a JPEG photo, most image editors decode the photo, rotate the bitmap and then re-encode it back to JPEG. This process slightly decreases the final image quality. Unlike those tools, the JPEG Lossless Rotator does not recode your photo and performs a special lossless block transformation instead. As a result, the rotated photo has the same quality as the original. In addition, JPEG Lossless Rotator has a very simple multilingual interface and is easy to use for inexperienced computer users.
