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. Shell integration feature. Free, simple, and useful.

Features:

• Shell integration (this allows you to rotate your JPEG photos by a right-click on the file)

• Batch rotation
• EXIF-data display
• Multilingual interface: Catalan, Chinese (simpl), Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Korean, Polish, Portuguese, Romanian, Russian, Slovak, Spanish and Swedish.
