- Google ad images require landscape (1.91:1), square (1:1), and optionally vertical (9:16) assets depending on campaign type.
- Performance Max needs a minimum of 7 images: 3 landscape, 3 square, and 1 portrait.
- All image files must be JPG or PNG and under 5 MB (5,120 KB).
- Google's built-in AI tool generates images from text prompts directly inside Google Ads — no design skills needed.
- Skip overlaid text and logos on image assets; Google layers copy through the ad format automatically.
- Upload 5 to 10 images per aspect ratio so Google can test and optimize combinations.
What are Google Ad Images and Where Do They Appear?
Google image ads run across the Google Display Network, which reaches over 3 million websites and 650,000+ apps. Three campaign types use images most.
Image ad formats across Google Ads campaigns
- Responsive Display Ads (RDA): Google combines your images with headlines and descriptions. Ads appear across the Display Network.
- Performance Max: Google's all-in-one campaign type. Images run across Search, Display, YouTube, Gmail, and Maps.
- Uploaded display ads: Static or animated files you design and upload directly. You control the final layout.
Why images matter for performance
Your image stops the scroll. A clear, product-focused image earns attention. A cluttered or low-res one loses the click before copy ever gets read.

Google Ad Image Specifications and Sizes
Get specs right before you design. Re-doing work because of a rejected upload wastes hours.
Standard image dimensions by ad format
Per Google's Ads Help Center, responsive display ads and Performance Max campaigns use three aspect ratios:
| Aspect Ratio | Type | Minimum Resolution | Recommended |
|---|---|---|---|
| 1.91:1 | Landscape | 600 × 314 px | 1200 × 628 px |
| 1:1 | Square | 300 × 300 px | 1200 × 1200 px |
| 9:16 | Vertical (optional) | See Google's docs | — |
Upload at the recommended resolution. Low-resolution images render poorly across placements.
File types and quality requirements
Google accepts JPG and PNG only. Maximum file size is 5 MB (5,120 KB) per image.
How many images you need
Performance Max campaigns require a minimum of 7 images: 3 landscape, 3 square, and 1 portrait. Responsive Display Ads require at least 1 landscape and 1 square image. Google recommends 5 to 10 images per aspect ratio for best optimization performance.

How to Create Google Ad Images: 5 Steps
Step 1: Choose your image source
Three paths: upload original photos, use Google's free Ad Gallery templates, or generate images with AI directly inside Google Ads. Each works. The fastest route depends on what assets you already have.
Step 2: Create or upload your image with correct dimensions
Design at recommended sizes. Export as JPG or PNG under 5 MB. Upload via the Google Ads Asset Library or directly during campaign setup in your asset group.
Step 3: Optimize for Google's best practices
Keep your product front and center. Blank space should not exceed 80% of the frame. Skip overlaid text, logos, and buttons. Google layers the copy through the ad format itself.
Step 4: Add images to your campaign
In your campaign or asset group, open the image assets section. Upload all required aspect ratios. Google mixes and matches assets to find the best-performing combinations.
Step 5: Test and iterate
Google recommends 3-4 ads per ad group. Upload multiple image variants per aspect ratio. Review performance in your Ads reporting dashboard and swap out low performers.

Using Google's Free AI Image Generation Tools
Google Ads now includes generative AI image creation built into the platform.
How Google's generative images work
Access the tool during campaign setup, in your asset group editor, or via the Asset Library. Enter a text prompt or supply a product photo. Google generates new images in seconds. It can also suggest images based on your landing page content.
Eligibility and limitations
Your account must be active for 30 or more days with a clean policy compliance history. The feature supports English and select other languages. Sensitive verticals including political ads, pharmaceutical products, and sexual content are excluded.
Tips for prompting effective images
Be specific. Include the product, the setting, and the mood. "A blue water bottle on a hiking trail, bright afternoon light" outperforms "a water bottle." Generated images include a SynthID watermark and are labeled as AI-created in Google Image Search.

Google Ad Image Best Practices
Per Google's best practices guide for responsive display ads:
- High quality only. Blurry or pixelated images are disapproved.
- No text overlays. Google layers copy through the format. Adding your own creates clutter.
- Product focus. Your product or service is the clear subject. Compositions with heavy blank space underperform.
- Use variety. Five to ten images per aspect ratio gives Google more combinations to test.

Speed Up Google Ad Image Creation with AI
Why manual image creation is time-consuming
Performance Max alone needs 7 images across three aspect ratios. Responsive Display campaigns benefit from 10 or more. Designing each from scratch takes hours, and that's before writing copy or building the campaign.
How AI tools accelerate the process
Coinis Image Ads workflow generates on-brand ad creatives from a product URL. Brand Profile captures your brand voice, colors, and messaging so every image stays consistent across every asset. You export creatives and upload them directly to Google Ads.
Coinis does not publish to Google Ads directly today. But the creative and copy production is where most campaigns stall. That part, Coinis handles fast.
