There are two places you can remove the background on your image:
1 - On the Brands page. Once you’ve uploaded your brand logo, you will be given the option to crop any space around your logo and also remove the background. You can then use this image in as many ideas are you like, it will automatically be uploaded there for you to use.
2 - When editing an ingredient. Once you’ve added your own image (or a stock image) to your ingredient, you can edit the image and use the background removal tool. You can also crop and adjust the image if you need to. This is more suited to on-off pictures you are unlikely to use frequently.
