Creating a JPEG image file is a relatively simple process, but something that is not often that simple is finding a way to change the orientation of the image without losing a large amount of information in the process. The main reason for this has to do with how image editors work. The majority of them will work on the process of decoding the image from JPEG to bitmap, rotating the bitmap and then recoding it for JPEG format. While there is nothing inherently wrong with this process, the double conversions from and to JPEG both carry with them minor calculation errors that when combined result in the loss of a little bit of image quality.

What makes the JPEG Lossless Rotator 6.3 so good as an image editing program is the fact that it does not utilize the conventional method for changing JPEG orientations. Instead, it applies a shell integration transformation to the entire image and as a result does nothing except change the orientation. This keeps the image quality the same and since the program itself is downloadable for free, anyone that wants to maintain the best quality JPEGs possible should certainly grab the latest version of this program which was released on March 22, 2009.

Features:

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