Use images with strong contrast
Faces, icons, silhouettes, logos, and objects on plain backgrounds usually work well. The converter needs clear dark and light regions to preserve shape.
Avoid cluttered backgrounds
Busy rooms, landscapes with too many tiny details, and low-light photos often become unreadable. Crop the subject before converting.
