FNSKU Label Generator

FNSKU Label Generator makes Amazon FBA barcode labels on your phone, with no account, no subscription and no internet connection. Type an FNSKU, get a scannable CODE128 label, and print it or send it as a PDF. That is the whole workflow. WHAT YOU CAN DO • Create labels in 4x6, 3x5 or 2x1 inch, the three sizes FBA sellers actually use • Watch a live preview update as you type • Print straight to a thermal label printer or any normal printer, at the exact label size with no margins • Export a real PDF and share it to WhatsApp, Gmail, Drive, Files or anywhere else on your share sheet • Save a PDF to your Downloads folder to keep or print later • Build a library of saved labels and reuse them as templates • Generate a whole batch from a CSV file • Calibrate margins once if your printer clips the edges • Switch between dark and light themes BUILT FOR SCANNING Barcodes are drawn as vector graphics, not images, so the bars stay perfectly sharp whether you print at 203 dpi on a thermal printer or 600 dpi on a laser. PDF pages come out at exactly 4x6, 3x5 or 2x1 inches with zero margins, so nothing shifts and nothing gets cropped. WORKS WITH NO SIGNAL The entire app is on your device. Warehouse with no reception, flight mode, prepaid data gone at the worst moment: it makes no difference. Nothing loads, nothing syncs, nothing waits. YOUR DATA STAYS YOURS This app requests no permissions at all, not even internet access, so it physically cannot send your product data anywhere. No account, no analytics, no ads, no tracking. Your labels and templates are stored on your device and nowhere else. When you share a PDF, it goes only to the app you pick. WHO IT IS FOR Amazon FBA sellers, prep centres, small warehouses and anyone who needs a correct FNSKU label without opening a laptop. NOT AFFILIATED WITH AMAZON This is an independent tool.
