The Ad Builder is a creative authoring tool that enables you to build HTML ads directly in Amazon Ad Server (AAS). Ad conception and animation does not require any coding knowledge. You can start with a blank ad or create a new ad using built-in templates, which are based on the most commonly used ad formats in the industry.



  • Ad Builder is compatible with the following browsers: Google Chrome, Mozilla Firefox, and Apple Safari.

  • HTML ads are available immediately in AAS when you create and save your ad in Ad Builder.

  • It is mandatory to configure a default image for each ad prior to saving the ad. The default image is limited to 300 KB.

  • The size of an HTML ad is the total size of all assets in the ad’s workspace, at the compressed size.

    • This includes images, the largest video, fonts, JavaScript files, HTML files, and any other files.

    • We do not count additional assets for dynamic creative or videos. For more information, see Add dynamic elements to your HTML ads using Ad Builder.

    • Compression is automatically applied, which reduces the size of each asset type to the compressed size.

  • When building a standard banner, only the following components will be available : Image, Text, Hotspot, HTML, Button, and Shape. For more information, see Create a standard banner in Amazon Ad Server Ad Builder.

Accessing Ad Builder

Ad Builder is accessible directly from AAS and does not require downloading or installation. You can access Ad Builder by navigating to this path in AAS: Creative > Ads > New Ad > Ad Builder.
