> Quick answer: Google Merchant Center requires clean, high-res product images on a white or neutral background. No watermarks. No promo text. No logos. Retouching fixes all of that before your ad goes live.
Poor product photos get disapproved before a single shopper sees them. Fix the image, fix the campaign.

Why Product Image Quality Matters for Google Ads
Google reviews every image before your product appears in Shopping results. Bad images mean disapprovals, lower CTR, and lost sales.
Google Merchant Center approval requirements
Per Google Merchant Center documentation, images must meet resolution minimums, show the full product clearly, and pass a content quality check. Low-res, cluttered, or text-overlaid images fail automatically. There is no manual appeal shortcut.
Impact on CTR, ad relevance, and conversions
90% of online shoppers are influenced by product visuals when making purchase decisions. High-quality images improve ad relevance scores in Google Shopping campaigns. Better images drive more clicks and more conversions.
Common image rejection reasons
Google most often rejects images for low resolution, overlaid promotional text, watermarks, visible logos, and cluttered or busy backgrounds. Every one of those is fixable with the right retouching workflow.

Google Ads Product Image Requirements
Know the specs before you start editing. Working to the wrong dimensions wastes your time.
Recommended image size and resolution
Google recommends 800 x 800 pixels or larger for Google Shopping product images. The maximum is 64 megapixels. The minimum is 100 x 100 px for non-apparel and 250 x 250 px for apparel products. Your product should fill 75 to 90% of the image frame.
Supported formats and file size limits
Per Google Merchant Center documentation, accepted formats include JPEG, PNG, WebP, GIF, BMP, and TIFF. Maximum file size is 16 MB. JPEG and PNG are the safest choices for quality and broad compatibility.
Background guidelines
A plain white or neutral background is strongly recommended for main product images. It improves CTR and reduces disapproval risk. Lifestyle or contextual images work fine as secondary images. Not the main one.
What NOT to include
Google prohibits promotional text, watermarks, and brand logos overlaid on product images. Any of these triggers automatic disapproval. Remove them completely before uploading.

6 Essential Retouching Techniques for Google Ads
These six edits cover most Google Ads rejections and performance problems.
Remove backgrounds or clean distractions
Replace messy or off-brand backgrounds with a clean white or neutral fill. This is the single most common fix for Google Shopping disapprovals. A clean background also focuses attention on the product.
Color correction and white balance
Accurate color is critical. A product that looks different in your ad than in real life drives returns and kills customer trust. Adjust white balance and color accuracy before touching anything else.
Blemish and dust removal
Small dust specks, fingerprints, and surface marks are invisible in person. They are obvious at 800 pixels. Remove them. A clean product looks more expensive and more trustworthy.
Object and watermark removal
Stray props, price tags, and old watermarks need to go. Google rejects images with watermarks. Erase them completely, not just cropped out of frame.
Sharpness and contrast enhancement
Flat or soft images hurt perceived quality. Boost contrast and sharpen edges to make the product stand out on mobile screens. Most shoppers see your ad on a phone first.
Resize to meet platform specs
Always export at 800 x 800 px or larger. Crop so the product fills most of the frame. A tiny product floating in a large white box wastes your ad placement.

Retouching Best Practices to Avoid Over-Editing
Maintain product authenticity
Do not smooth every texture or dramatically shift colors. The product must look like what the customer receives. Over-editing creates returns and negative reviews.
Start with high-quality originals
Retouching improves a decent photo. It cannot rescue a blurry one. Shoot at the highest resolution possible. Good lighting cuts your editing time in half.
Consistency across product variants
If you sell the same item in five colors, all five images should match in framing, lighting, and background. Inconsistency looks unprofessional and hurts brand credibility.
Test across devices before uploading
Open the finished image on your phone and your desktop. Problems invisible on a large monitor are obvious on mobile. Catch them before Google does.
