A FORMAT THAT SUITS YOUR IMAGE
The file's aspect ratio, resolution and crop determine the format that can genuinely be used. An image that looks sharp on a phone or screen may lack detail once enlarged. Send the largest, least compressed original version you have, without enlarging it artificially.
If the file proportions do not match the required format, you must choose between an explicitly approved crop and retaining the entire image with margins. The selected orientation and crop are checked before production.
