Photo CC let you lossless transform JPG (JPEG) photos. You get the same quality of images as your original photos.
With Photo CC, you can:
Crop your photo with the selection area;
Flip your photo horizontally or vertically;
Rotate your photo to left (90 degree), to right (-90 degree), and upside down (180 degree);
Change your photo to grayscale (black & white).
All these transformations are LOSSLESS. The program never touch your original photos.
