SellaFit — Bulk Image Resizer for Sellers by Mrrage

SellaFit resizes a whole shoot of product photos to marketplace-ready specs in one pass — entirely in your browser. Your photos never leave your device.

• One-click presets: Amazon (2000×2000, white pad), Etsy, eBay, Shopify square
• Plain-English batch renaming (original name + number, store + number, and more)
• Exports every image, or the whole batch as a ZIP
• Free for up to 5 photos per batch; a one-time $15 unlock removes the limit and adds saved presets + rename patterns

100% private: all processing runs locally in your browser. No uploads, no accounts, no tracking, no ads.
