When you add images to a Batch, Photoroom automatically imports them and removes their backgrounds. If you want to keep the original backgrounds, apply the Original image template.
Steps (iOS)
In the Batch Editor:
Create a new batch or work with the batch you already have open.
Select Templates.
Select From Photoroom.
Scroll down and select See all templates.
In the Classics collection, select the image with the full background.
[Optional] Use the Batch Editor to make further changes.
