When you take a digital photo of a statue or Eiffel tower you mostly use portrait format instead of landscape. But when you capture your very moment of a beautiful beach you will take a photo using landscape format.
To display an portrait format of digital images full screen on your computer, you need to rotate it 90o before you can enjoy those image. Now imagine, if you have thousand of images on your digital image storage but they are stored on different image format i.e. portrait and landscape. How pity if you can’t rotate those images just in one action.
However many people don’t realize when they 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 other image viewer tools JPEG Lossless Rotator does not recode your photo but performs a special lossless block transformation. As a result, the rotated photo has exactly the same quality as the original.
The nice feature of this free software is Shell integration (this allows you to rotate your JPEG photos by a right-click on the file), Automatic rotation, Batch rotation, EXIF-data display, and 13 Multilingual interface.
