JPEG Lossless Rotator

Do you know that rotating a photo using Windows Photo Viewer or other picture viewers can result in quality loss? This might come as a surprise to you but it is true. The loss is minimal in such a way that the quality remains the same when seen with naked eyes.

Let me elaborate. When the image is rotated, Windows Photo Viewer will automatically save it. Remember that JPEG format uses compression, which means that every time you save the photo, it be compressed. If it is compressed one or two times, then you won’t see any difference in image quality, but try saving the same image over and over again around 20 times and you will see some noticeable quality loss.

In short, it means that when you rotate and save the JPEG photo the quality is NOT the same as original photo. So what is the solution to this problem? There are many JPEG lossless rotating tools, but I would recommend using JPEG Lossless Rotator due to it’s ease-of-use.

Once installed, it will integrate itself to the Windows Explorer right-click context menu. It also has a basic User Interface where you can add the images and then rotate them together, but rotating via context menu is much faster.

    • Yes you would expect they would have fixed this by now.

      I know that in the old days it was lossy, and you had to use a 3rd party program like Xnview which had a “JPG lossless rotate” feature.

      It should have been trivial to implement this functionality by now, it’s been around for that many years. I’d be very sad if it wasn’t, as I’ve been primarily using Windows 7 Gallery for everything.
