What you get

Tools built for marketplace and creator work — with defaults that match common listing and inbound rules — while your files stay on your device.

Ready for the platform

Amazon listing sizes, FBA carton limits, and more presets aimed at what Seller Central and shops actually expect — less guesswork before you upload or ship.

Your files stay private

Processing runs in your browser. Product photos and carton numbers are not uploaded to our servers. You can verify in DevTools → Network.

Batch when you need it

Prep several listing images or check multiple cartons in one pass, then download or review results without creating an account first.

Free to start

Core use is free with soft batch limits. Upgrade later only if you need larger runs across the whole site.

Found a problem? Get free usage credit

If a tool breaks, looks wrong, or fails your workflow, tell us. Confirmed useful bug reports earn a free usage credit (for example, higher batch limits while we fix it). No account required to report.
