Quick answer: Google Ads rejects images that are blurry, text-heavy, or off-spec. Get the right dimensions, clean up your photo, and upload multiple sizes. Here is the full workflow.

Why Product Photo Quality Matters in Google Ads
Your product photo is the first thing Google's automated review sees. A weak image gets restricted or rejected before any human ever looks at it.
How images affect ad approval and performance
Google scores your ad creative as part of Ad Strength. Higher scores mean broader serving eligibility. Per Google's Ads Help Center, uploading 4 to 10 images per aspect ratio maximizes Ad Strength and your chances of serving across placements.
Common issues that fail Google's review process
Most rejections trace back to the same problems. Text overlays on the image. Button graphics that simulate clicks. All-white or digitally composite backgrounds. Blurry, color-inverted, or heavily filtered photos. Per Google's best practices guide for Responsive Display Ads, every one of these triggers disapproval.

Google Ads Image Specifications by Campaign Type
Getting the specs right is non-negotiable. One wrong dimension and your image will not serve.
Responsive Display Ads sizing and requirements
You need at least one horizontal and one square image. Horizontal (1.91:1): recommended 1200x628, minimum 600x314. Square (1:1): recommended 600x600, minimum 300x300.
Performance Max image requirements
Performance Max has stricter volume requirements. Per Google Ads documentation on Performance Max asset groups, you need at least 4 horizontal and 4 square images. Horizontal: recommended 1200x628, minimum 600x314. Square: recommended 1200x1200, minimum 300x300.
Demand Gen campaign specifications
Demand Gen recommends 3 horizontal images (1.91:1 at 1200x628) and 3 square images (1:1 at 1200x1200).
Aspect ratios and file formats
All Google Ads images must be JPG or PNG. Maximum file size is 5MB. Those two rules apply across every campaign type.

How to Prepare Your Product Photo for Google Ads
A few quick fixes before you resize can prevent hours of re-submission.
Assess image resolution and quality
Start with the highest-resolution version of your product photo. Anything blurry, filtered, or skewed will fail Google's automated quality check. Use the original file, not a screenshot or compressed export.
Crop and center your product
Keep your product in the center 80% of the image. Per Google's documentation, content outside this zone may be cut off across different device screen sizes. Tight crops work well. Just leave a small margin at every edge.
Remove backgrounds or add context
All-white and digitally composite backgrounds raise review flags. Google's Responsive Display Ads guide states that physical settings with natural lighting perform better. Remove the plain background and place the product in a real or naturally lit scene.
Avoid text overlays and logos
Do not add text, logos, or button graphics directly onto the image file. Google treats these as policy violations in responsive formats. Your headline and description fields are the right place for copy.

Resize and Format Your Image to Spec
Choose the right aspect ratio for your campaign
Match your campaign type to the specs above. Running Performance Max? Prepare both 1200x628 and 1200x1200 versions. Running Responsive Display? Same rule applies.
Resize without losing quality
Scale down from your largest source file. Never scale up from a small image. Scaling up creates blur that can trigger a quality rejection.
Save as JPG or PNG under 5MB
JPG is fine for product photography. PNG works better for images with sharp edges or transparency. Keep the file under 5MB or Google will reject the upload on the spot.
Prepare multiple sizes if needed
Uploading 4 or more unique images per aspect ratio improves Ad Strength. It also gives Google more options to match the best creative to each placement automatically.

Quality Checks Before Upload
Run this checklist before you upload anything.
Review focus and clarity
Open the image at 100% zoom. Is the product sharp? Any motion blur? Fix it before uploading.
Confirm colors are accurate and natural
Color-inverted or heavily filtered images fail quality review. What you see in the file should match what the product actually looks like.
Ensure product is the focus, not blank space
Blank space must not exceed 80% of the image. A small product floating in a large white background will likely get flagged.
Verify file size and format
Check the file properties. JPG or PNG. Under 5MB. That is the whole checklist.

Upload Your Image to Google Ads
Where to upload in each campaign type
For Responsive Display Ads: go to your ad group, select "New ad," then "Responsive display ad." Upload images in both aspect ratios. For Performance Max: open your campaign, navigate to the Asset groups section, and add images when building or editing an asset group. For Demand Gen: images are added during ad creation inside each ad group.
Creating asset groups
Performance Max and Demand Gen campaigns organize creatives into asset groups. Add all your image sizes to one asset group. Google automatically selects the best combination for each placement.

Frequently Asked Questions
What image size does Google Ads require?
It depends on the campaign type. For Responsive Display Ads, the recommended sizes are 1200x628 (horizontal, 1.91:1) and 600x600 (square, 1:1). For Performance Max, Google recommends 1200x628 and 1200x1200. All images must be JPG or PNG under 5MB.
Can I put text on my Google Ads image?
No. Google's policy prohibits text overlays, logos, and button graphics on product images in responsive formats such as Responsive Display Ads and Performance Max. Add your copy to the headline and description fields in the ad builder instead.
How many images should I upload to a Performance Max campaign?
Google requires a minimum of 4 horizontal (1.91:1) and 4 square (1:1) images per asset group. Uploading 4 to 10 unique images per aspect ratio improves Ad Strength and gives Google more combinations to test across placements.
