FEATURES Automatic Everything: Import a photo or take one using your iPhone camera. The app automatically crops, rotates, and adjusts it to meet the specific requirements of your selected application. Ensure your face is evenly lit, without glasses or head coverings (except for religious reasons), and free of dark shadows. A simple background is also recommended.

 Need finer control? Simply drag or pinch the photo within the frame to adjust the crop as needed. Seamless Exporting:
 Your photo is application-ready with just a tap! Export it or save it directly to your Photos library. Important Note:
