TL;DR: Google Shopping ads pull images from your Merchant Center product feed automatically. Display ads need custom creatives in three aspect ratios. Use Coinis Image Ads to generate both sets from your Shopify product URLs, then upload directly to Google Ads or Merchant Center.

Two Paths for Google Ad Images on Shopify: Shopping Ads vs. Display Ads
Google gives Shopify merchants two very different ad types. Each one has its own image workflow and its own specs. Knowing which you need saves time.
What Shopping ads are and how they pull images from your feed
Shopping ads appear at the top of Google search results. They show a product image, title, price, and store name.
Per Google Ads Help, Google builds Shopping ads automatically from your Merchant Center product feed. You don't design a Shopping ad. You submit product data, including images, and Google does the rest.
Your job is to supply great product images in your feed. The ad creative is largely hands-off after that.
What Display ads are and when to use custom images
Display ads run across the Google Display Network. Think banner placements on websites, apps, and YouTube.
For Display ads, you upload your own images. Google combines them with your headlines and descriptions to create Responsive Display Ads (RDAs). The system tests combinations and serves the best-performing ones.
You need at least one image in each supported aspect ratio to compete across all placements.
Which path is right for your business
Run Shopping ads if you sell physical products and want to capture high-intent search traffic. Run Display ads if you want to build awareness, retarget site visitors, or promote a sale.
Most Shopify merchants run both.

Image Requirements for Google Shopping Ads on Shopify
Good product images are your most important Shopping ad asset. Google uses them to build your ads automatically.
New minimum size requirements (500x500 by Jan 2027)
Per Google Merchant Center Help, the new minimum image size for Shopping ads is 500x500 pixels. This requirement takes effect January 31, 2027.
Plan for this now. If your current product images fall below that threshold, start replacing them before the enforcement date.
Recommended sizes for best performance (1500x1500+)
Merchant Center recommends 1500x1500 pixels or above for best performance across all listing formats. Larger images look sharper on high-resolution screens and in prominent placements.
Use 1500x1500 as your baseline. Square format works best for Shopping.
File format and quality guidelines
Google Merchant Center accepts JPG and PNG files. Maximum file size is 16 MB.
Images must be clear, high-quality, and accurately represent the product. Generic stock photos or graphics are not allowed for most product categories. Per Google Ads policies, all images must accurately represent the advertised product or service.
How to add product images to your Shopify feed
Shopify connects to Google Merchant Center through the Google and YouTube app. Once installed, it syncs your product catalog automatically.
Make sure your Shopify product photos are high-resolution, square, and free of watermarks before syncing. What you upload in Shopify is what Google shows in Shopping ads.

Image Requirements for Google Responsive Display Ads
Responsive Display Ads give you reach across millions of placements. To maximize that reach, you need images in three aspect ratios.
Three aspect ratios: horizontal (1.91:1), square (1:1), vertical (9:16)
Horizontal images appear in wide banner placements. Square images work across most standard display placements. Vertical images are used in portrait-oriented mobile and app placements.
Covering all three aspect ratios means your ads appear in more placements. More placements mean more reach at the same budget.
Recommended and minimum pixel dimensions for each
Per Google's Ads Help Center, the recommended and minimum dimensions are:
Horizontal (1.91:1)
- Recommended: 1200x628
- Minimum: 600x314
Square (1:1)
- Recommended: 1200x1200
- Minimum: 300x300
Vertical (9:16)
- Recommended: 900x1600
- Minimum: 600x1067
Always use the recommended sizes. Minimum-size images often look poor in high-visibility placements.
File size and format limits (JPG, PNG, max 5MB)
Google Display ads accept JPG and PNG only. Maximum file size is 5,120 KB (just over 5 MB).
Compress images to stay under the limit without losing visible quality. Most professional product photos compress well at 80-90% quality in JPG.
Best practices: focus, clarity, no overlaid text or logos
Per Google's best practices guide for Responsive Display Ads, do not overlay text, logos, or buttons on your images. Google assembles your ad from separate image and text assets. Overlaid elements confuse the system and hurt performance.
Images must show natural lighting and real-world settings. Avoid all-white backgrounds for Display ads. Avoid collages, digital composites, and excessive filters.

Best Practices for Creating High-Performing Google Ad Images
The spec requirements are the floor. These practices push performance higher.
Use high-quality, clear product photography
Blurry or poorly lit images hurt click-through rates. Use crisp, well-lit photos. Natural lighting beats over-processed studio setups for most product categories.
If your current photos are low-resolution, Coinis Revise includes AI Upscale. It sharpens and enlarges images without the blur that standard resizing creates.
Avoid collages, composite backgrounds, and excessive filters
Google's documentation is clear on this. Collages, digital composite backgrounds, and heavily filtered images all hurt Responsive Display Ad performance.
One product. One clean background. Full focus on what you're selling.
Highlight your product, not blank space
Blank space must not exceed 80% of the image. Per Google's best practices guide for Responsive Display Ads, the product should be prominent and easy to identify at a glance.
If your image has too much negative space, crop it tighter. Your product should command the frame.
Create 5-15 images per aspect ratio for A/B testing
Google's machine learning optimizes ad combinations over time. But it needs material to work with.
Google recommends uploading 5-10 images per aspect ratio for best performance, and up to 15. The more quality variations you provide, the more Google can learn and optimize.
Include a clear logo and brand name
Display ads should include a logo in a 1:1 or 4:1 aspect ratio. Google's documentation recommends using a simple, clean logo paired with your brand name.
This builds recognition over time. Shoppers who see your brand repeatedly are more likely to convert later.
