Hi,

Thank you for reaching out to the DocuSign Community.

By default, your stamp uses a circle crop. If your image is square, select the Change Shape button and then select the Square Crop option to switch to a square window.

 For the best results from a square crop, your image should be square, with a 1:1 aspect ratio.

Please keep in mind that, that there's no way to have the system save the Stamp Image to a size larger than 15mm, if your image is larger than that limit, you will have to manually resize the tag if you would like it any larger.
