What is the face oval guide?

The oval overlay shows the ideal face position in the frame. Zoom in or out until your face fits inside the oval — this ensures your face occupies the correct proportion of the photo.

What does Center Face do?

It automatically detects your face and centers the frame around it. Click it after uploading for the best starting position.

What does Straighten do?

It detects the angle of your eyes and rotates the image so they are perfectly level — useful for photos taken at a slight tilt.
