Flexible Ads
Combine 2-10 images and/or videos into a single ad container. Meta automatically selects whether to show each user a single image, video, or carousel.
Accessing the Builder
After uploading media, the Build Flexible Ads button appears in the toolbar above the uploaded media table. This is the default builder shown in the toolbar.
To switch to the Carousel Ads builder, click the dropdown arrow next to the button and select Build Carousel Ads.
How It Works
Upload media to your library, then use the Flexible Ads builder to group assets into containers. Each container becomes a single ad that Meta optimizes for format delivery.
