Are you looking to upload a GIF to your Google Display Ads? You're in luck! Google Ads allows you to upload image ads such as GIF, JPG, and PNG. This offers more granularity for displaying individual images that you can report on than for responsive search ads. However, there are some specifications for standard image ads in Google Ads that you should be aware of. Acceptable image types include GIF, JPG, and PNG with a maximum size of 150 KB. Please note that sizes vary by pixel and style.
For example, a standard square image ad should be 250x250px or 300x600px. If the problem was related to an incorrect animation, it wouldn't be validated later, but you can still upload GIFs to your campaign. Ads must be in PNG, JPG or GIF* format. Your ad size should not exceed 150 kb. Additionally, Google Ads does not allow text (including logos with text) that covers more than 20% of the image or animated images (such as GIFs) and will not be accepted.
