Google ads live or die by image quality. Raw product photos almost always need resizing, reformatting, or cleanup before they pass Google's approval checks. This guide walks you through every step.
Why Google Ads Need Optimized Product Photos
Google rewards high-quality, relevant images across every ad format. A properly optimized photo means better eligibility, more placements, and stronger performance.
Google rewards high-quality, relevant images with better ad eligibility and performance
Per Google's Ads Help Center, image assets on Search campaigns can boost click-through rate by 6% on average. That only happens with approved, high-quality images. Low-quality photos get disapproved or simply underperform.
Product photos must work across multiple ad formats
Google Display, Search, Shopping, and Performance Max all use images differently. Each format has its own size requirements and quality standards. One raw photo rarely fits all of them without preparation.
Most advertisers fail by uploading raw product photos without optimization
Common results: disapproved images, cut-off content, or blurry renders on high-resolution screens. Taking five minutes to prep your photo prevents all of these.
Step 1: Prepare Your Product Photo
Start with the photo itself before touching any campaign settings.
Check image quality
Your photo needs sharp focus, good lighting, and accurate colors. Blurry or poorly lit photos will underperform even if they pass approval. Per Google's best practices guide for responsive display ads, natural lighting and physical settings outperform digital composites.
Ensure the full product is visible and centered
The product should fill the frame. Minimal blank space. No awkward cropping. Google's policy requires important content to sit within the center 80% of the image.
Choose natural backgrounds or physical settings
Avoid pure digital white backgrounds. Google's image asset documentation specifically calls out overly white backgrounds as a quality issue. Natural settings or neutral surfaces work better.
Remove logos, watermarks, or text overlays
Overlaid logos, buttons, or promotional graphics violate Google's image asset policies. Let the product do the work. Text naturally embedded in the product (like a label) is fine. Added graphic overlays are not.
Step 2: Resize and Format for Google's Requirements
Per the Google Ads Help Center, these are the specs you need for Display and Performance Max campaigns.
Square format (1:1): 1200×1200 pixels minimum
This is the recommended size for Display and Performance Max. The minimum accepted is 300×300px, but use 1200×1200px for quality across all devices.
Landscape format (1.91:1): 1200×628 pixels minimum
Landscape images unlock more ad placements. Use 1200×628px as your baseline. Smaller sizes (minimum 600×314px) are accepted but rarely look sharp on modern screens.
Use JPG or PNG, max 5MB per file
Google accepts JPG and PNG for standard image assets. Keep each file under 5MB. Larger files are rejected automatically.
Place important content in the center 80%
Google crops images differently for different placements. Anything in the outer 20% of the frame may get cut. Keep your product centered and clear.
Step 3: Upload to Your Google Ads Campaign
Once your images are prepped and sized, head into Google Ads.
Search and Display campaigns: up to 20 images per campaign
Google's documentation allows up to 20 diverse, high-quality images for Search and Display image assets. Upload multiple crops and variations to give Google's algorithm more to work with.
Performance Max campaigns: 4+ square and 4+ horizontal images recommended
Google recommends at least 4 square and 4 horizontal images for Performance Max. More variety means more placement opportunities across Google's network.
Shopping and Merchant Center: 1500×1500px or above
Per Google Merchant Center documentation, 1500×1500 pixels or above is strongly recommended for Shopping listings. The minimum is 500×500px, but larger images perform significantly better on high-resolution screens.
Verify approval before launch
Google reviews all image assets before they serve. Check the status column in your asset library. Disapproved assets include a reason. Fix the issue and resubmit.
Common Mistakes to Avoid
Small errors cause big delays. Watch for these.
- Blurry or pixelated images. Google disapproves them. Use original high-res files.
- Collages or composite images. Single, clean product shots perform better and have fewer approval issues.
- Excessive blank space. More than 20% blank edge hurts performance and can trigger disapproval.
- Text or button overlays. Graphic text added in editing gets flagged. Remove it before uploading.
- Logo-only images. A logo without a product photo does not qualify as an image asset.

Frequently Asked Questions
What image sizes does Google require for Display and Performance Max ads?
Google recommends 1200×1200px for square (1:1) and 1200×628px for landscape (1.91:1). The minimum accepted sizes are 300×300px and 600×314px respectively, but the recommended sizes give you the best quality across all placements and devices.
Can I use a product photo with text overlays in Google Ads?
No. Google's image asset policies prohibit added text overlays, buttons, or promotional graphics. Text that is naturally part of the product, like a label, is fine. Graphic overlays added during editing are not and will likely cause disapproval.
How many images should I upload for Performance Max campaigns?
Google recommends at least 4 square images and 4 horizontal images for Performance Max. More variety gives Google's algorithm more to test and optimize across different placements.

Not yet. Coinis publishes directly to Meta (Facebook and Instagram) today. Google Ads direct publishing is on the roadmap. You can generate and export Google-ready creatives from Coinis using Image Ads and Revise, then upload them to Google Ads manually.
