Do my images get uploaded to your servers?

No, absolutely not. Vcour is a 100% browser-based tool. All image processing, compressing, and watermarking happen directly on your device. Your files never leave your computer, guaranteeing total privacy for your unreleased product photos.

How does the Anti-AI watermark work?

Our Anti-AI watermark applies an advanced, subtle grid pattern over your images. This pattern is designed to confuse automated AI scraping tools and background-removal software, making it extremely difficult for competitors or dropshippers to steal and reuse your original product photography.

Which e-commerce platforms is this optimized for?

Vcour's preset dimensions and auto-square features are perfectly tailored for major marketplaces including Shopify, Etsy, Amazon, WooCommerce, and various Print-on-Demand (POD) platforms.

How does the Smart SEO Naming feature help me?

Vcour allows you to set a base keyword and automatically renames your entire batch sequentially (e.g., leather-sling-bag-01.jpg). This tells Google Images exactly what your product is, significantly boosting your organic search traffic.

How many images can I process at once?

You can process up to 20 images simultaneously in a single batch. Since everything runs locally in your browser's memory, this limit ensures maximum speed and prevents your browser from crashing.

💡 Audit Recommendations

Common Non-Compliance Patterns

The following patterns are frequently detected during compliance audits and may result in feed disapproval if not addressed.

"Image Too Small"

Appears not to meet the 100×100 pixel minimum requirement (250×250 for apparel).

Audit Note: Images must meet minimum dimension requirements to be eligible for Google Shopping. Upscaling low-resolution sources is not recommended; use original high-resolution assets.

"Promotional Overlay on Image"

Possible text ("Sale"), brand logo, or barcode detected layered over the product.

Audit Note: Google Merchant Center guidelines prohibit promotional overlays, watermarks, and logos. Branding should be confined to feed text attributes only.

"Blurry Image / Low Quality"

Heavy compression or poor focus may have degraded pixel integrity below acceptable thresholds.

Audit Note: Excessive lossy compression destroys fine detail. Use high-quality source files and export at appropriate compression levels.

Marketplace Image Requirements Reference (2026)

If you distribute your catalog across multiple platforms, standardizing your images to the strictest requirements will minimize feed rejections. Below is a reference comparison of major marketplace image specifications.

Marketplace	Best Dimensions	Background Requirement	Max Weight
Google Merchant	2000 × 2000 px	Pure White (RGB 255)	16 MB
Shopify	2048 × 2048 px	Transparent/White	20 MB
eBay	1600 × 1600 px	Pure White	12 MB
Etsy	2000px (5:4 Ratio)	Lifestyle accepted	10 MB
TikTok Shop	1080 × 1080 px	Clean/Contextual	5 MB

Frequently Asked Questions

Does Google allow watermarks on Merchant Center images?

No. Google Merchant Center guidelines prohibit watermarks, store logos, or copyright symbols. These may result in feed disapproval.

What is the best format to upload?

WEBP and optimized JPG are the best formats. PNG is supported but typically creates file sizes that are too heavy, causing slower page loads and feed API timeouts.

Can Google Merchant Center reject an image even if the size is correct?

Yes. Meeting the minimum dimensions is just one requirement. Images can still be rejected due to poor image quality, promotional overlays, watermarks, blurriness due to compression artifacts, or a non-white/transparent background. The technical compliance assessment evaluates multiple quality and policy dimensions beyond pixel dimensions.

Does Google Merchant Center allow transparent PNG product images?

Yes, Google Merchant Center supports PNG images with transparency. However, while supported, a pure white background (RGB 255) is generally recommended for apparel and non-apparel products. Transparent PNGs can sometimes be rendered with a black background in some retail contexts, so a white background is often considered the safer and more uniform choice for Shopping ads.

What is the best image resolution for Google Shopping products?

While the minimum size is 100×100 pixels, Google recommends images with dimensions of at least 800×800 pixels for high-quality display. For apparel, a 2000×2000 pixel resolution is strongly recommended as it enables zoom functionality and appears sharp on high-DPI displays. Higher resolution images generally lead to better customer engagement.
