Google Ads includes AI-powered image generation built right into the platform. You don't need a designer or a photo studio to get started. This guide covers the native workflow, the specs you need, and a faster path to production-ready creatives.
How Google Ads Generates Images Natively
Per Google's Ads Help Center, Asset Studio lets you generate new images, replace backgrounds, auto-enhance photos, and resize to every needed format, all from inside your Google Ads account.
Using Asset Studio to create product images
Asset Studio is Google's central creative hub. Upload a product photo, write a text prompt describing a scene, and Google AI generates new images placing your product in that exact setting. The finished images land in your Asset Library and are ready to attach to any campaign.
Google AI image editor: backgrounds, enhancement, auto-resize
The image editor handles more than generation. Swap backgrounds on existing photos. Auto-enhance image quality in one step. Add objects to a scene. Auto-create all the sizes you need for Google's different placements. No manual resizing required.
Accessing the tools and workflow
Open your Google Ads account and go to the Tools menu. Find Asset Studio there. Navigate to the "Personalize your images with Google AI" section and select "Create product images." Follow the prompt flow to generate your first image.
Image Specifications and Requirements for Google Ads
Wrong specs mean missed placements. Per Google's Ads Help Center, every campaign needs at minimum one landscape and one square image to maximize serving eligibility.
Minimum landscape and square image requirements
The minimum landscape ratio is 1.91:1. The minimum square ratio is 1:1. You need at least one of each. Missing either format cuts your ad's reach across certain placements. Google recommends four unique images per ad group for better distribution across audiences and inventory.
File formats and size limits
Upload only JPG or PNG files. The maximum file size is 5 MB. Files over that limit will fail on upload. Compress your images before uploading and verify the file size beforehand.
Recommended dimensions for broad reach
The recommended landscape size is 1200 x 628 pixels. The recommended square size is 1200 x 1200 pixels. These dimensions give Google enough resolution to serve your ad cleanly across desktop, mobile, and partner sites.
Best Practices for High-Converting Ad Images
Strong creative follows a few firm rules. Apply them to every image you generate, whether you use Google's native tools or anything else.
Quality and authenticity
Google flags low-quality images in policy review. Avoid screenshots, mockups, and heavily stylized photos. Real-looking, high-resolution images pass review faster and tend to perform better. Keep text off the image itself. Google Ads applies your headlines and descriptions as separate assets for responsive ads. Text baked into the image conflicts with that system.
Brand consistency across image variations
Test multiple variations, but keep them visually coherent. Same color palette. Same product framing. Similar overall aesthetic. Audiences see your ads across many placements. Consistency builds recognition faster than constantly shifting visuals.
Relevance to keywords and audience
Match your image directly to what the user searched. A keyword about running shoes needs a running shoe image, not a lifestyle shot of a city street. Direct relevance improves Quality Score and can lower your cost per click over time.

Frequently Asked Questions
What image sizes does Google Ads require?
Google Ads requires at least one landscape image at a 1.91:1 ratio and one square image at a 1:1 ratio. The recommended sizes are 1200 x 628 pixels for landscape and 1200 x 1200 pixels for square. Both must be JPG or PNG and under 5 MB.
Can I use AI-generated images in Google Ads?
Yes. Google Ads includes its own AI image generation through Asset Studio. You can also generate images with third-party tools and upload them manually, as long as they meet Google's file specs and comply with its advertising policies.
Should I include text in my Google ad images?
No. Google Ads applies your headlines and descriptions as separate text assets for responsive ads. Text overlaid on the image itself can conflict with that system and may hurt your ad's quality rating.
How many images should I upload per ad group?
Google recommends four unique images per ad group or campaign to maximize serving eligibility and reach across different placements and audience segments.
