When you build your asset group, add quality, relevant images that complement your ads and help visually describe your business. Image assets include your logos and other images to help attract people to your business and personalise your ads. You can even use the image assets that you create on search campaigns with your Performance Max campaigns.
Image specifications
Make sure that you review the guidelines below before creating your image asset to avoid disapprovals. Images must also meet image asset format requirements. Images go through quality and policy checks before being eligible to serve. You can read more About the ad review process.
In addition to the requirements listed in the table below, all image assets must meet the following requirements:
- Saved as a JPG or PNG file
- Maximum file size of 5 MB
- Content needs to be in the centre 80% of the image (the safe area that won’t be cut off despite device screen size)

*Logos with a transparent background may be rendered on a white background when served in most ads. For this reason, we recommend you upload logos as a square image and to avoid a predominantly white logo on a transparent background. |

You can use images with overlays, but it's recommended to use at least one image without overlays for each aspect ratio (square, horizontal and vertical). Here are some examples:

After you upload your assets, be sure to monitor how they’re performing. Wait about two to three weeks to check on your ad strength and asset group status, then evaluate if you need to replace low-performing assets. Learn more about Asset group best practices.
Note: By creating image assets, you are confirming that you own all legal rights to the image and have permission to share the image with Google to use on your behalf for advertising or other commercial purposes.

Image asset best practices
Along with a focus on quality and specifications, you should experiment with the types of content that you use in your ads and how they showcase your message. Here are a few of our best practices for image assets:
- Use both image assets and dynamic image assets.
- Add four or more unique images at the ad-group level.
- Square images are required for ads, but be sure to use images with varying aspect ratios in your ads.
- Make sure to add images relevant to the queries and ads that they’ll be shown with.
- Use your images to convey your unique selling feature.
