# SDXL Background Replacement for Product Images
_from your friends at 🛍️[Shopify](https://www.shopify.com/)_
Building an online store requires lots of high quality product and marketing images. This is an early demo of a background replacement tool built with Stable Diffusion XL that makes it easy to use your existing product images to make something new. Please be patient during peak demand. 😅
To use it, upload your product photo and describe the background you’d like to see in place of the original. Optionally, describe what you don’t want in the negative prompt field.
