## What Square Online asks for, covered.

Square recommends item images of at least 2,000 × 2,000 pixels in a 1:1 ratio. Square 2K output is 2,048 pixels wide, just above that. Square 4K output is 4,096 pixels wide, above the 2,560 × 2,560 maximum the UK edition of Square's article states, so 2K is the size to upload there. Herofab images can be downloaded as PNG or JPG.

### Square, above 2,000
