You can use our 'Remove Image Backgrounds' automation to remove backgrounds from images in bulk. You will need to configure a remove.bg API key in your workspace settings.
Setup
Prepare an attachment field containing the original images and a separate attachment field for the processed images.
Create this automation and select the Airtable base and table you want to use.
Add your Remove.bg API key in Workspace settings, then select it under Remove.bg API Key in this automation.
Set Original Images Airtable Field to the source attachment field and Images Without Backgrounds Airtable Field to the output attachment field.
Review Processing Behavior if the output field already contains values. Only choose to overwrite data you intend to replace.
In Run, limit processing to a view containing one or two test records. Run the automation and inspect the processed images in Airtable before processing more records.
