ChatGPT Ad Image Requirements
ChatGPT ads require a square 1:1 image. Here are the complete technical requirements and creative guidelines.
Technical specifications
- Dimensions: 1200 x 1200 pixels (square 1:1)
- Format: PNG or JPG
- Maximum file size: Check current OpenAI Ads documentation
- The image should be publicly accessible via URL for bulk upload
Creative guidelines
The image should reinforce the same customer situation, problem, or outcome expressed in the title and copy. It should have a clear focal point and avoid unnecessary text or visual clutter.
Do not use landscape images. The primary ad asset must be square 1:1.
