Free simple image converter that rotates JPEG images without any loss in quality
Free, simple, and useful utility that rotates JPEG images without any loss in quality. Unlike many image editors, this utlity does not decode and encode back a JPEG image while rotating, that keeps quality of rotated images at the original's level.
When you want to rotate a JPEG image or photo, most image editors decode the image, rotate the bitmap and then reencode the JPEG. This process slightly decreases the final image quality. But, unlike other tools, this does not recode your image but performs a special lossless block transformation. As a result, the rotated image has exactly the same quality as the original. Two possible thumbnail quality/speed settings, shell integration feature (this allows you to rotate a JPEG image through a right-click on the file), batch rotation (from the shell), EXIF-data display, and favorite folders option. Free, simple, and useful.
