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
• Optional: remove the background — the product on pure white, or transparent, centered in the frame
• 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

About background removal: it needs a one-time download of the cutout engine (about 91 MB) from sellafit.mrrage.dev. Nothing is downloaded unless you press "Download the engine", and you can delete it any time. The engine runs on your computer, so your photos are still never uploaded. Everything else works without it.

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

No paywall at the end: anything you make on the free plan downloads for free.
