On the Web App, you can download all of the product images for multiple products at once. You'll need to switch your Product catalog to list view and then you can select the products you want and download.
Steps (Web App)
To download the images for multiple products at once:
Make sure the Product catalog is set to show the list view. For instructions, see Display the Product catalog in grid view or list view (Web App).
Select all of the products you want to download.
Select Download images.
Photoroom downloads the images as a zip file. When you extract the zip file, you will see that Photoroom has created a folder for each product with the product's images inside.
Troubleshooting
Missing products in download
If you have two products with the same name, Photoroom will only download one of the products. To fix this, make sure your products have unique names.
Important: For downloads, Photoroom ignores the case of the title characters. So a product named "product_ABC" is seen as identical to a product named "Product_abc".
