If you want to do more than just a clockwise or counter-clockwise turn when it comes to rotating images, reaConverter's Auto Rotate feature is what you are looking for. This advanced feature not only allows you to change an image from a portrait to a landscape position, but also to deskew an image with text and to rotate using EXIF information. Not to mention it's really easy and fast to operate!
Open Images

Auto Crop
In the Edit images tab, go to the Add action button, and then to Alteration and Orientation. Here pick Auto Rotate.
You will now be able to select from several options available in connection to rotating your image, such as using an Antialiasing device to avoid image distorsions, deskew an image with text in case its lines are misaligned, rotate landscape to portrait or vice-versa. An additional option lets you rotate the image using the EXIF (Exchangeable Image File Format) orientation information embedded in the image file.
