One tool to catch image blunders before marketplace uploads
Marketplace sellers can now run a quick, private pre-flight on product photos before they ever hit upload. ListingPic, a browser-based tool, scans an image against the sizing, aspect-ratio, file-type and safe-area rules of major sales channels—without ever sending the photo to a server. The goal is to surface problems like thumbnails that crop out the product, wrong ratios for previews, or risky positioning that violates Amazon’s main-image guidelines, so sellers adjust once instead of re-uploading repeatedly.
Hidden hurdles in cross-channel reuse
A single product photo rarely works the same way across Etsy, Amazon, TikTok Shop, Shopify, eBay and Walmart. ListingPic highlights where a photo may be too small for a channel’s thumbnail, too wide for a square preview, or positioned too close to the edge for safe-area rules. The tool frames issues in seller-friendly language—“Will the product be cut?” or “Will this hurt my listing?”—rather than pixel counts, aligning with how merchants actually think about images.
Privacy-first design for sensitive assets
Because many sellers deal with unreleased SKUs, branded shots or client assets, ListingPic processes images entirely in the browser. No upload means faster checks and no central storage of sensitive files. The MVP already covers Etsy, Amazon and TikTok Shop, with entry points for Shopify, eBay and Walmart workflows.
Sellers and indie makers can try it at listingpic.com and share feedback on missing checks, batch processing or the toughest marketplace rules.
Why it matters
Image problems discovered post-upload can stall listings or trigger manual reviews, costing time and conversions. A lightweight, privacy-preserving pre-check shifts that risk upstream and reduces the cycle of upload-preview-delete-resize. For platforms and sellers alike, it’s a practical hedge against the hidden formatting friction that turns a good photo into a listing headache.
