- Google disapproves ad images that are blurry, pixelated, or poorly lit — fix them before uploading.
- Square images need at least 300×300px. Landscape images need at least 600×314px.
- Aim for 1024×683px or higher to stay sharp after cropping and resizing.
- Google's built-in AI upscaler helps borderline images but requires a decent source to begin with.
- Coinis Revise AI Upscale fixes low-resolution photos in one click before you submit to Google.
- Start with well-lit, high-resolution source images. Enhancement tools fill gaps, not fundamentals.
A low-quality photo doesn't just look bad. Google will reject it outright. Knowing what Google requires, and fixing images before you upload, saves time and keeps campaigns running.
Why Image Quality Matters in Google Ads
How Google evaluates image quality
Google reviews every uploaded image against its editorial and technical standards. Per Google's Ads Help Center, images flagged as blurry, pixelated, or poorly lit violate the image quality policy and will not run.
What causes disapproval: blurriness, pixelation, poor lighting
The most common disapproval triggers are:
- Blurry or out-of-focus images
- Pixelation from heavy compression or over-upscaling
- Poor lighting that obscures the product or subject
- Cropping issues that cut off key elements
Google's creative enhancement features also require high-quality base assets. A damaged source image won't benefit from Google's AI enhancements.
Impact on ad performance and clickthrough rates
Sharp images drive better engagement. A blurry creative signals low effort to users and to Google's automated ranking systems. Getting image quality right from the start protects both approvals and performance.
Understanding Google Ads Image Requirements
Minimum size requirements and why they matter
Per Google's Ads Help Center, square images must be at least 300×300px for Performance Max and Demand Gen campaigns. Landscape images for Responsive Display Ads must be at least 600×314px. Images below these thresholds cannot be used in a campaign.
Recommended resolution for best results
Meeting the minimum won't keep images sharp across all placements. Google's own image guidelines recommend at least 1024×683px, with 2048×1366px or higher as the ideal. Higher resolution gives Google more to work with when it crops and resizes across placements.
Supported formats and file size limits
Google Ads accepts JPG and PNG for image ads. The maximum file size is 5MB per image. Compress files carefully. Aggressive compression introduces artifacts that can trigger quality flags.
How Google's built-in AI upscaling works
Google Ads includes an AI upscaling feature. When an uploaded image falls below the minimum size requirement, Google uses premium AI models to resize and sharpen it. This is a safety net, not a strategy. Per Google's documentation, it works best on images that are already reasonably sharp and well-lit.
How to Enhance Low-Resolution Ad Photos Before Upload
Assess your current image quality and resolution
Check your image dimensions and file quality before uploading. Most photo editing apps display pixel dimensions. If your image is below 600×600px, plan to upscale it before use.
Upscale images using AI tools to meet Google's standards
AI upscaling tools rebuild lost detail rather than simply stretching pixels. The result holds up much better at larger sizes. Aim to reach at least 1024×683px on the output, even if your source was smaller.
Sharpen and improve clarity to avoid disapproval
After upscaling, apply light sharpening. Edges should be crisp. Subjects should read clearly at a glance. Avoid over-sharpening, which creates harsh halos around edges.
Compress file size while maintaining quality
Export at the highest quality your file size allows. PNG preserves detail well. JPG at 80-90% quality usually hits the right balance. Stay under the 5MB cap without visible artifacts.
Best Practices for Keeping Ads Sharp and Clear
Start with high-quality source images
Enhancement tools can recover a borderline image. They can't rescue a fundamentally poor photo. Shoot or source images at full resolution from the start.
Avoid text-heavy or small details that blur easily
Fine print and small logos lose legibility when resized. Google's guidelines flag images where key information becomes unreadable. Keep text large and bold, or leave it out of the image entirely.
Test images across different placements and sizes
One image renders across multiple placements at different aspect ratios. Check how your image looks cropped to square, landscape, and portrait. What looks sharp at full size may fall apart at 300×300px.
Use proper lighting and contrast in your photos
Well-lit images pass quality checks more reliably. High contrast between subject and background improves visibility. Flat or dim images often fail Google's editorial review.
What to Do If Your Ad Is Disapproved for Image Quality
Re-upload a cleaner, higher-resolution version
Disapproval is not permanent. Fix the image and re-upload. Replace blurry assets with sharper versions at the recommended resolution.
Address specific issues: blur, pixelation, cropping problems
Google's disapproval notification usually names the issue. Match the fix to the flag. Blurry image: upscale and sharpen. Pixelation: re-export at higher quality. Cropping: reframe the composition.
Appeal Google's decision with improved assets
If you believe your revised image meets all requirements, you can submit an appeal through Google Ads. Attach the improved asset and reference the relevant quality specs in your appeal notes.

Frequently Asked Questions
What is the minimum image size for Google Ads?
Square images need at least 300×300px for Performance Max and Demand Gen campaigns. Landscape images for Responsive Display Ads need at least 600×314px. Images below these thresholds won't run. For the sharpest results across all placements, aim for 1024×683px or higher.
Why does Google disapprove my ad image?
Google disapproves images that are blurry, pixelated, poorly lit, or have cropping issues. These violations fall under Google's image quality policy. Fix the issue in the source file and re-upload. Google's built-in AI upscaler can help borderline images, but it works best when the source is already reasonably sharp.
Does Google Ads automatically upscale images?
Yes. Google Ads has a built-in AI upscaling feature that resizes and sharpens images that fall below the minimum size requirements. It uses premium AI models to improve the image. However, this feature works best with decent source material. A heavily compressed or blurry original will not upscale cleanly.
What file formats does Google Ads accept for images?
Google Ads accepts JPG and PNG image files. The maximum file size per image is 5MB. Compress your files carefully to stay under the limit without introducing visible artifacts or quality loss.
