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.

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.
