The problem

You have a landscape photo that needs to be a square post, or a horizontal image for a vertical story. Cropping cuts the best part. Stretching looks awful.

The fix

Upload your image. Pick Instagram Post or Story. Choose fit, crop, or expand. Download in the exact dimensions Instagram requires.
