Marketplace Image Checker

Yes. The checker runs in your browser with no signup, credits or paywall. GenImagePro CTAs only appear when a visual problem cannot be fixed reliably with local resize, crop or compression.

No. Analysis and conversion happen locally in your browser. Original files are not uploaded, stored or used to train AI models.

At launch we check Amazon, Etsy, Shopify, eBay, Walmart Marketplace, TikTok Shop and Google Merchant Center. You can compare one image against several platforms at once.

Amazon, Walmart, TikTok Shop and Etsy treat the first or main image differently from gallery images. White-background and presentation rules should not be applied to lifestyle or secondary shots.

It measures dimensions, aspect ratio, file size, format, megapixels, orientation, transparency, approximate white-background coverage, edge color and whether the file is animated. Blur, text overlays and prohibited content stay as manual checks in version one.

Yes. You can resize, crop, add padding, convert formats, compress, flatten transparency and export a separate optimized file for each selected marketplace as a ZIP.

No. A pass means measurable technical rules succeeded. Always complete the manual policy checklist for text, props, accuracy and category rules before publishing.

Each rule stores a source, region, image role and last-reviewed date. We update the rule set when official marketplace guidance changes.

Many marketplaces reject or poorly display images below their minimum pixel size. Resize upward only if the source has enough detail, or recreate the photo at a higher resolution.

Square crops and tight marketplace frames can clip edges. Add padding or recompose so the product sits safely inside the thumbnail safe area.

Upload limits vary by platform. Compress locally or convert to JPEG/WebP while keeping quality high enough for zoom.

Amazon, Walmart and similar marketplaces often require a seamless white background on the main image. Lifestyle shots belong in secondary slots.
