Image Spec Check
Free image size checker for any marketplace, no upload

Hey Product Hunt 👋
I'm the maker of Image Spec Check. I kept running into the same annoying problem: a product photo would look fine, then get rejected at upload — wrong dimensions, wrong ratio, file too big, or it got awkwardly cropped in the thumbnail. Every marketplace has slightly different rules, and checking them by hand is tedious.
So I built a free checker. You drop in an image and it instantly tells you:
• ✅ / ❌ on dimensions, aspect ratio, format, and file size
• A crop preview showing how it'll actually look in the listing thumbnail
• One-click resize, compress, and export to a clean upload file
It covers Amazon, Etsy, Shopify, eBay, Walmart, TikTok Shop, and YouTube, with a general website checker too.
Two things I care about: it's 100% free with no signup, and your images never leave your browser — everything runs client-side, nothing is uploaded or stored.
Would love your feedback — especially which other platforms or rules you'd want added. Thanks for checking it out! 🙏
