Technical Specifications
Before thinking about content, make sure your images meet Google's technical requirements. A technically compliant image that violates a content rule is still disapproved — but at least fixing technical issues is straightforward.
| Requirement | Specification |
|---|---|
| File format | JPEG (.jpg / .jpeg), WebP, PNG (.png), GIF (.gif), BMP (.bmp), TIFF (.tif / .tiff) |
| Minimum size (non-apparel) | 100 × 100 pixels (absolute minimum; Google recommends 800 × 800+) |
| Minimum size (apparel) | 250 × 250 pixels (Google requires higher quality for fashion) |
| Recommended size | 800 × 800 pixels minimum; 1,000+ × 1,000+ for best ad performance |
| Maximum file size | 16MB per image |
| Maximum dimensions | 64 megapixels (total pixel count) |
| Animated GIFs | Allowed; use the first frame as the representative image |
| Transparency | Transparent backgrounds are allowed; Google may render them on a white or colored background |
While 100×100px is technically allowed, Google's algorithm favors high-resolution images in ranking and display. Images below 400×400px often receive lower quality scores internally. Standardize on 1,000×1,000px or 1,200×1,200px for all your main product images. It also future-proofs your feed for any resolution requirement increases.
What's Prohibited in GMC Images
These are the content rules that cause the most disapprovals. Many are obvious in hindsight, but easy to overlook when you're pulling images from supplier libraries or designing your own product shots.
Promotional Overlays and Text
This is the #1 image disapproval cause. Any text overlaid on the image is prohibited — regardless of content. This includes:
- Sale percentage banners ("50% OFF")
- Price tags overlaid on the image
- Shipping callouts ("FREE SHIPPING")
- Brand name or logo overlaid in text form
- Product name text
- Any promotional messaging
Dropshippers and resellers frequently use supplier-provided images that have the supplier's logo or watermark embedded. These are disapproved immediately. Never use supplier images with any branding, watermarks, or overlaid text in your GMC product feed. You must either get clean images from the supplier or remove overlays yourself.
Watermarks
Any visible watermark — stock photo watermarks, supplier logo watermarks, photographer credits — will cause disapproval. Use only images you own or have proper licensing for without watermarks.
Placeholders and Generic Images
Images that are clearly placeholders — camera icons, question marks, color swatches instead of product photos — are not acceptable. Each product must have a real, specific product image.
Multiple Products in Main Image (When Selling One)
If you're selling a single product, the main image should primarily feature that one product. Including multiple products in a "lifestyle grouping" where it's unclear which product is being sold can trigger disapproval. (Additional images can show the product in context with other items.)
Inappropriately Cropped Images
Images where the product is cut off or significantly cropped will be disapproved. The full product (or the main view of it) should be visible. Leave reasonable padding around the product — don't fill 100% of the frame edge-to-edge.
Blurry or Low-Quality Images
Images that are clearly blurry, pixelated, or poorly lit can be disapproved under Google's quality standard. This is more subjective than other rules, but images that are clearly not professional quality are at risk.
Inappropriate Image for Product Type
Using a lifestyle image when Google's policy requires a product-only image (or vice versa, for apparel) will cause disapproval. See the apparel rules section below.
Lifestyle Images vs White Background: What Google Prefers
This is one of the most nuanced areas of GMC image policy, and the answer has changed over the years as Google has refined its requirements.
For most non-apparel products:
Google does NOT require a white background for non-clothing products. You can use lifestyle images, colored backgrounds, or contextual settings. However, Google does recommend that the product is clearly the focal point — backgrounds shouldn't be so busy that they obscure the product.
That said, white or very light backgrounds tend to perform better in Shopping ads because:
- The product stands out more clearly in the ad unit
- Google's responsive ad system has more flexibility with light backgrounds
- Light backgrounds are consistent across different display contexts
For apparel products:
Google's official policy for apparel products (category: Apparel & Accessories) specifically requires either:
- A model wearing the clothing (on-model shot), OR
- The clothing presented as a flat lay on a solid, neutral background
White or off-white backgrounds are strongly preferred. Stock imagery from suppliers that shows clothing on a hanger is often disapproved if it's low quality or doesn't clearly show the garment details.
Special Rules for Apparel Products
Apparel has the strictest image requirements of any product category in GMC. If you sell clothing, shoes, or accessories, pay close attention to these specific rules:
Main product image requirements for apparel
- Must be an on-model shot OR a flat lay on a neutral background
- Minimum 250×250px (though 800×800+ is strongly recommended)
- No promotional text overlays
- No visible watermarks
- Product must be the main focus — no heavily styled lifestyle imagery where the garment is secondary
Color variants and the image_link vs additional_image_link strategy
For products with multiple color variants, each variant should have its own image showing the correct color. Showing a blue image for a product listed as red is a policy violation. Use variant-specific product entries with variant-specific images for accurate representation.
Showing a product image in a different color, size, or style than what the customer receives is treated as misrepresentation by Google — not just an image quality issue. For apparel with variants, every color/size variant in your feed should link to an image that accurately depicts that specific variant.
Additional Images and the additional_image_link Attribute
Most sellers only populate the main image_link field. But Google supports up to 10 additional images per product via the additional_image_link attribute. These are used in:
- Rich Shopping ad carousel formats
- Free listing expanded views
- Dynamic remarketing creative assembly
Additional images are held to the same content standards as main images (no watermarks, no overlaid text), but you have more flexibility with lifestyle images in the additional slots. Use them to show:
- Product from multiple angles
- Product in use / lifestyle context
- Size and scale reference images
- Detail/zoom shots of key features
- Packaging and unboxing
Adding additional images is a low-effort, high-impact feed improvement. Many stores see better ad engagement with multi-image listings.
Most Common Image Disapprovals and Fixes
"Image too small"
Cause: Image dimensions below minimum requirements (100×100px for non-apparel, 250×250px for apparel).
Fix: Upload higher-resolution images. If you only have small images, photograph or re-source product images at a higher resolution. Don't artificially upscale — Google can detect and may still disapprove upscaled low-quality images.
"Promotional overlay text detected"
Cause: Text, prices, or promotional banners overlaid on the image.
Fix: Remove all text overlays and re-upload clean product images. For images from suppliers with embedded text, request clean versions or photograph products yourself.
"Image quality too low"
Cause: Blurry, pixelated, poorly lit, or otherwise low-quality image.
Fix: Replace with professionally photographed images. A basic product photography setup (white background, proper lighting) produces images that meet GMC quality standards.
"Invalid image URL" or "Image not crawlable"
Cause: The image URL in your feed is broken, returns a 404 error, or is behind authentication.
Fix: Verify all image URLs are accessible without authentication. Check for broken links using a link checker tool. Make sure your CDN is configured to serve images publicly.
"Watermark detected"
Cause: A visible watermark (stock photo, supplier brand, photographer credit) in the image.
Fix: Use only images where you have rights and there are no watermarks. For stock photography, use properly licensed images (not preview/watermarked versions).
Bulk Image Optimization Strategy
For stores with large catalogs, fixing image issues one by one isn't practical. Here's an efficient approach:
- Audit by disapproval type: In GMC → Products → Diagnostics, filter by "Image" issue type. Export the list to identify which products have image problems and what kind.
- Prioritize by revenue impact: Fix images for your highest-selling or highest-margin products first. A disapproved image on a $500 product is a bigger loss than one on a $10 product.
- Batch by image type: If the main issue is promotional overlays, batch-process all images through a tool that removes overlaid text. If the issue is resolution, set up a process to re-source or re-photograph at scale.
- Use feed rules for image_link updates: If you need to swap image URLs in bulk, GMC's feed rules feature can help you apply substitutions across large product sets without changing your source feed.
- Schedule regular image audits: New products are added with potentially non-compliant images. Build a monthly image audit into your GMC maintenance workflow.
