Note: This feature is available only, if you have loaded a JPG file.

 

 

Click on the Options Menu, then JPG Lossless Rotation. A dialog allows you to rotate, flip, optimize or clean one or many JPG files.

 

Note: You can process many JPG files, if you open the Thumbnails window and select several JPGs before you start this dialog.

 

 

Note: Lossless JPG operations like flip or rotate work only if the image height is a multiple of 16 (JPG specification). If this is not the case, unused image lines will be removed.

 

 

Note: Your original JPG file will be changed/overwritten!

 

 

Click Start to transform the loaded JPG or Cancel to exit.
