JPEG Lossless Rotator
JPEG Lossless Rotator is a very simple free tool letting you rotate JPEG images without spoiling their quality.
What makes the program especially valuable is that, unlike many other image editors, JPEG Lossless Rotator preserves the original image quality after rotation. The program avoids the usual JPEG decoding-encoding process and performs a special kind of transformation instead.
JPEG Lossless Rotator has a user-friendly interface which makes the whole process very fast and easy. The program lets you browse your computer to locate a folder or a file you would like to work with. Thumbnails of the selected images are displayed on the right panel. You just highlight the thumbnail of the image that you want to rotate and then select the rotation type: Left, Right, or 180. The image will be rotated at once and the changes displayed immediately. You don’t have to save the rotated image if you would like to keep it as it replaces the original image automatically.
