The Compress command will open up and you will see several options. The first option is the Quality setting. You can choose between Low, Medium or High quality compression. The second option is the File Size setting. You can choose between Small, Medium or Large file size. The last option is the File Format setting. You can choose between JPEG, PNG or TIFF file format. The final step is to click on the OK button to compress your photo. ..
