- iPhone photos default to 4:3 ratio and HEIC format, both of which Google Ads rejects.
- Google requires a 1:1 square crop and recommends a 1.91:1 landscape crop for maximum reach.
- Recommended sizes are 1200×1200 px (square) and 1200×628 px (landscape), under 5 MB, JPG or PNG.
- Keep your subject inside the center 80% of the frame, with no text overlays or logos on the image.
- Coinis Revise Smart Resize outputs both aspect ratios at once, no manual cropping needed.
- Performance Max campaigns require at least 7 image assets across landscape, square, and portrait formats.
iPhone photos look great on your camera roll. Getting them into Google Ads is a different story. The platform has strict size, format, and aspect ratio requirements, and your phone photo almost certainly won't pass on the first try.

Why Your iPhone Photo Needs Adjustment for Google Ads
iPhone photos vs. Google's image requirements
Modern iPhones shoot at 12 to 48 megapixels. That is far more resolution than Google Ads needs. The bigger problem is aspect ratio. iPhones default to a 4:3 ratio. Google Ads requires 1:1 square and 1.91:1 landscape crops. Your photo needs to be cropped and resized before it can run.
File size and format considerations
iPhone photos save as HEIC by default. Google Ads does not accept HEIC. You need JPG or PNG. File size must stay under 5 MB. Most unedited, full-resolution iPhone shots sit above that limit.
Aspect ratio and cropping needs
Google runs your image across multiple placements. Each placement uses a different crop. Supplying both a square and a landscape version gives you the widest reach. Miss one, and your ad skips entire networks.

Google Ads Image Specifications You Must Know
Required aspect ratios (1:1 square, 1.91:1 landscape)
Square (1:1) is required for Responsive Display Ads and Search image assets. Landscape (1.91:1) is strongly recommended for maximum reach. Per Google's Ads Help Center, both together give you the best placement coverage.
Recommended image dimensions and minimums
For Responsive Display Ads, Google recommends 1200×1200 px for square and 1200×628 px for landscape. Minimums are 300×300 px and 600×314 px respectively. Aim for the recommended sizes. Minimum-size images can look soft in high-resolution placements.
For Performance Max, Google requires at least 7 image assets total, including 3 landscape, 3 square, and 1 portrait image.
Supported file formats and size limits
JPG and PNG only. Maximum file size is 5,120 KB (5 MB) per Google's documentation. JPG is the best choice for photos. It compresses efficiently and stays well under the limit.
Campaign types that use image assets
Image assets power Responsive Display Ads, Search campaigns (with image extensions), Demand Gen, and Performance Max. Each campaign type has slightly different asset requirements. Performance Max is the most demanding, with 7-image minimums.

How to Resize and Optimize Your iPhone Photo for Google Ads
Step 1. Choose your primary aspect ratio
Start with the square (1:1) crop. It satisfies the required format and works across the most placements. Then prep the landscape (1.91:1) for broader reach.
Step 2. Crop and resize using Coinis Revise (Smart Resize)
Open your photo in Coinis Revise. Select Smart Resize. Choose both aspect ratios. Both files come out spec-ready in seconds. No manual cropping. No guessing pixel counts.
Step 3. Check quality and apply AI Upscale if needed
Smart Resize previews the crop before you export. If the resized image looks soft, use AI Upscale inside Revise. Cutting-edge AI models restore detail without introducing noise.
Step 4. Export in the correct format
Export as JPG for photos. Choose PNG only if your image needs a transparent background. Either way, verify the file size is under 5 MB before moving on.
Step 5. Upload to your Google Ads campaign
Go to your Google Ads campaign. Navigate to image assets and upload your files. Google runs automated quality and policy checks before your ad starts serving. Sharp, natural images with no text overlays clear these checks fastest.

Best Practices for Phone Photos in Google Ads
Keep the image sharp and natural
Blurry, filtered, or color-shifted images fail Google's quality checks. Per Google's best practices guide, use images shot in good light with no distortion, no heavy filters, and no digital composites.
Keep your subject in the center 80% of the frame
Google's documentation is clear on this. Keep your product or subject inside the center 80% of the image. Edges get cropped unpredictably across placements. Center the shot when you take it, or crop to center before you upload.
Avoid text overlays, logos, and filters
No text on the image itself. No logo burned in. Google's system flags these. The photo should carry the visual message on its own. Ad copy and your business name go in the text fields, not on the creative.
Create both square and landscape versions
Upload at least one square and one landscape image. Google recommends 5 to 10 images per aspect ratio for Responsive Display Ads. More variations give the system more to test against your audience.

Frequently Asked Questions
Can I use iPhone HEIC photos directly in Google Ads?
No. Google Ads only accepts JPG and PNG files. HEIC is not supported. Convert your photo to JPG before uploading. Most export tools, including Coinis Revise, handle this automatically.
What is the minimum image size for Google Ads?
For Responsive Display Ads, the minimum is 300×300 px for square and 600×314 px for landscape, per Google's documentation. Aim for the recommended sizes of 1200×1200 px and 1200×628 px for best results across all placements.
Do I need both square and landscape versions of my photo?
For the widest reach, yes. Square (1:1) is required for most ad types. Landscape (1.91:1) is strongly recommended. Google uses whichever fits the placement. Missing one format means your ad skips entire networks.
How many images does Google recommend for best performance?
Google recommends 5 to 10 images per aspect ratio for Responsive Display Ads. Performance Max requires a minimum of 7 total images across landscape, square, and portrait formats.
