- Google's native image upscaling works inside Performance Max, Demand Gen, Search, App, and Display campaigns.
- Sharp, well-exposed images at correct dimensions improve Ad Strength, CTR, and conversions.

Why Image Quality Matters in Google Ads
Bad images cost you clicks. Google's own documentation confirms the link between image quality and measurable performance.
Impact on Ad Strength and performance metrics
Per Google's Ads Help Center, quality images used in the correct dimensions help improve Ad Strength, CTR, conversion rate, and total conversions. Ad Strength is Google's real-time signal for how well your creative is likely to perform. Low-quality visuals drag that score down.
Google's standards for image clarity and sharpness
Google requires high-quality, sharp image assets with no exposure or cropping issues for image enhancement features to activate. Blurry or poorly exposed images can be limited in delivery. Some may be rejected outright.
Common issues that hurt ad performance
The three main killers are blurriness, bad aspect ratio cropping, and poor exposure. Each one limits where your ad can run. Fix them before you upload, not after.

Google's Native Image Enhancement Tools
Google includes upscaling directly inside the campaign workflow. No third-party tool needed for basic resizing.
Image upscaling in Performance Max and Demand Gen
The Google Ads image upscaling enhancement increases image dimensions while maintaining image integrity to meet minimum campaign requirements. Google introduced this feature specifically to handle images that are close to spec but fall slightly short.
How upscaling maintains quality
Google's upscaling preserves sharpness while increasing pixel dimensions. It does not stretch or distort the image. It's built for images that are nearly spec-ready, not for images that are very low resolution to begin with.
Which campaign types support enhancements
Image enhancement features are available in Performance Max, Demand Gen, Search, App, and Display campaigns. That covers the majority of Google Ads inventory, per the Google Ads AI features update from September 2024.

Image Requirements and Best Practices
Get the specs right before you upload. Wrong specs mean rejected assets or limited delivery.
Recommended resolution and file size
For uploaded image ads (banner-style), Google's Advertising Policies require a file size of 150 KB or smaller. For image assets used in Responsive Display Ads and Performance Max campaigns, the maximum file size is 5 MB per Google's Ads Help Center. Know which ad type you are building before you start.
Image formats
Google accepts JPG and PNG for image assets in Responsive Display Ads and Performance Max campaigns.
Dimensions for different ad formats
For Responsive Display Ads, the minimum is 600 x 314 px for landscape images and 300 x 300 px for square images, per Google's Ads Help Center. For Performance Max, you need at least seven image assets total: three landscape, three square, and one portrait. Keep all key content inside the center 80% safe zone. Content outside that area may get cropped across placements.

Advanced Image Enhancement with Coinis Revise
Google's native tools handle quick fixes. Coinis Revise handles everything else.
When native tools aren't enough
Google's upscaling works for images that are already close to spec. It won't rescue a badly blurred source file. It won't let you swap text on the image or remove an unwanted object. For those edits, you need a proper AI image editor.
AI Upscale for low-resolution source images
Coinis Revise includes AI Upscale. Upload a low-resolution product photo and it outputs a sharp, high-resolution version ready for Google Ads. The premium AI models handle detail reconstruction that basic scaling cannot do.
Batch enhancement and quick iterations
Revise also includes Variate, which generates multiple creative versions of a single image fast. Test different crops, color treatments, or text overlays without rebuilding from scratch each time. More variants means more data on what actually performs.
Integration with Google Ads workflow
Coinis does not publish directly to Google Ads today. That's on the roadmap. Right now, Revise is your pre-upload creative layer. Enhance images in Revise, download them, then upload directly to Google Ads. The turnaround is fast.

Step-by-Step: Enhance and Launch Your Google Ad Images
1. Prepare your source image
Start with the highest-resolution version you have. Check it against the specs above. If it's blurry, underexposed, or badly cropped, note the specific problem before you proceed.
2. Enhance using Coinis Revise or Google's tools
Low-res source file: use AI Upscale in Coinis Revise. Need to change text on the image: use Edit text on image. Need to remove a logo or watermark: use AI Erase. Download the finished file when you're done.
Image is nearly spec-ready and just needs a small size bump: use Google's native upscaling inside the campaign interface.
3. Verify specs and upload to Google Ads
Check file format (JPG or PNG), resolution, file size (150 KB for uploaded image ads, 5 MB for image assets), and safe zone coverage. Then upload to your campaign and confirm the asset is approved.
4. Monitor performance
Watch Ad Strength after upload. If it stays low, image quality may still be the limiting factor. Run a Variate in Coinis Revise to test a fresh creative version alongside the original.
