Quick answer: Pull your best Amazon product image, upscale to at least 1500x1500px, verify it meets Google's frame and format rules, and upload it via Merchant Center. Or skip the prep and generate a spec-ready image from your product URL with Coinis Image Ads.

Why Image Quality Matters for Google Ads
Better images mean more clicks. Full stop.
Performance lift and CTR benchmarks
Per Google's Ads Help Center, adding image assets to search campaigns drives a 6% average CTR increase. For Shopping and Performance Max, the image is the ad. A poor product shot costs you clicks before a single word of copy lands.
Policy compliance and disapproval risks
Google disapproves images for blurriness, excessive whitespace, logos covering the product, and policy violations. A disapproved image asset can stall your entire ad group. Getting specs right before upload saves hours of troubleshooting later.

Google's Product Image Requirements
The specs are precise. Match them before you upload anything.
Merchant Center minimum specs (current and 2027 enforcement)
Per Google's Merchant Center Help, current minimums are 100x100px for non-apparel and 250x250px for apparel. That changes on January 31, 2027. From that date, all products must meet a 500x500px minimum. Google recommends 1500x1500px for best performance across all formats. Max file size is 16 MB or 64 megapixels. Note the deadline now. Listings below 500x500px after that date will be hard-disapproved.
Google Ads image asset format requirements
Performance Max campaigns use three image ratios. Square (1:1) at 1200x1200px is required. Landscape (1.91:1) at 1200x628px is recommended. Vertical (4:5) at 960x1200px is optional but expands your placements. Accepted formats include JPEG, PNG, WebP, GIF, BMP, and TIFF. Per Google's image asset policy documentation, important content must sit inside the center 80% of the frame. The product must occupy 75 to 90% of the image area.
Special considerations for Amazon feed data
Amazon images typically use white backgrounds, which works for Merchant Center. But Google's guidelines recommend lifestyle images for the additional_image_link attribute. White-background-only shots can underperform on Performance Max placements that favor contextual or environmental images. If your Amazon A+ content or brand store has lifestyle shots, bring them in.

Step-by-Step: Preparing Your Amazon Product Images
Do this before you open Merchant Center.
Assess your current Amazon images
Download your highest-resolution Amazon listing image. Amazon requires at least 1000px on the longest side for main images. That often falls short for Google. Check whether you have the original photography file at higher resolution before requesting a reshoot.
Verify resolution and file format
Open the image and check the pixel dimensions. If it lands below 1500x1500px, upscale it or source a new export from your photographer. Convert to JPEG or PNG if the file is another format. Remove any watermarks, seller badges, or FBA stickers before upload.
Optimize composition and product staging
Google requires the product to fill 75 to 90% of the frame. If your product looks small or floats awkwardly in a large white field, crop it. Tighten the composition without trimming the product itself. Avoid excessive whitespace along any edge.
Check for policy violations
Per Google Ads policy documentation, images must not include promotional text, prices, or phone numbers unless you also submit at least one clean version per aspect ratio. Check every overlay. A single policy flag disapproves the asset and can cascade to the campaign.

Creating or Sourcing New Images (If Needed)
Sometimes your Amazon images simply won't meet Google's bar.
High-resolution product photography
Commission a product photographer to shoot at 2000px or higher against a neutral or lifestyle background. This gives you raw files flexible enough for every Google placement, plus Amazon simultaneously.
AI-generated product images
Cutting-edge AI models now generate photorealistic product images from a URL or product description. Coinis Image Ads does exactly this. Paste your Amazon product URL. The AI analyzes the product and produces multiple performance-ready images sized for Google Ads placements. No photography. No design software. Download the files and upload them directly to Merchant Center or your Performance Max campaign.
Note. Coinis generates and exports your creatives. Direct publishing to Google Ads is on the Coinis roadmap. You upload the finished images to Google yourself today.
Using existing lifestyle or context images
If you have lifestyle images from Amazon A+ content or brand stores, use them. Submit them via the additional_image_link attribute in your Merchant Center feed. Google treats these as supplemental assets for Performance Max and Shopping placements.

Uploading and Testing in Google Merchant Center
Getting the image into your feed correctly is its own step.
Adding image_link attribute to your feed
Use the image_link attribute for your primary product image. The URL must be stable, crawlable, and RFC 3986 compliant. No timestamps. No session parameters. Google crawls these URLs on its own schedule. A broken or blocked URL disapproves the product listing automatically.
Testing with URL inspection tool
Use the URL inspection tool inside Merchant Center to confirm Google can crawl your image URL. If it returns an error, check your robots.txt file and server response headers. Google must reach the image directly without problematic redirects.
Monitoring for disapprovals or warnings
Check the Diagnostics tab in Merchant Center at least once a week. Image disapprovals surface there first. A warning about image size today becomes a hard disapproval after January 31, 2027. Fix undersized images before that deadline, not after.

Best Practices to Maximize Performance
A few habits keep your images working hard over time.
Submit multiple images and aspect ratios
Google recommends at least 4 images per campaign or ad group for Performance Max. Upload square, landscape, and vertical crops of your strongest shots. More variety gives Google's algorithm more to test and more placements to fill.
Use dynamic image assets
Enable dynamic image assets in Performance Max campaigns. Google pulls additional images directly from your landing page. Make sure your product page or external listing has high-quality images accessible to crawlers, not hidden behind JavaScript renders.
Monitor CTR and refresh underperformers
Watch image-level performance in your asset report. Drop images with low CTR after sufficient data accumulates. Replace them with new variations shot from different angles or generated with different backgrounds. Treat image creative the same way you treat ad copy. It stales.

Frequently Asked Questions
What image size does Google require for Shopping and Performance Max ads?
Google recommends 1500x1500px for best performance. The minimum today is 100x100px for non-apparel and 250x250px for apparel, but a new 500x500px minimum applies to all products starting January 31, 2027. Performance Max also accepts landscape (1200x628px) and vertical (960x1200px) assets.
Can I use my Amazon product photos for Google Ads directly?
Often yes, with some prep. Amazon main images typically have white backgrounds that work for Merchant Center. But check that the image is at least 1500x1500px, the product fills 75 to 90% of the frame, and there are no overlays violating Google's image asset policies. Lifestyle images from your Amazon A+ content are worth adding via the additional_image_link attribute.
What file formats does Google Merchant Center accept for product images?
Google Merchant Center and Google Ads accept JPEG, PNG, WebP, GIF, BMP, and TIFF. Maximum file size is 16 MB or 64 megapixels. Image URLs must be stable, crawlable, and RFC 3986 compliant with no timestamps or session parameters.
What happens if my product images are disapproved in Google Merchant Center?
Disapproved images prevent that product from serving in Shopping or Performance Max campaigns. Check the Diagnostics tab in Merchant Center to see the specific reason. Common causes include image size below minimums, policy-violating overlays, blurry or distorted images, and uncrawlable URLs. Fix the issue, reupload, and request a re-review.
