Frequently asked questions

Which barcode type should I use?
Use Code 128 for general text and numbers — it is the most versatile. Use EAN-13 or UPC-A for retail products, and Code 39 when a system specifically asks for it.
What about the EAN/UPC check digit?
Enter the first 12 digits for EAN-13 (or 11 for UPC-A) and the final check digit is calculated and added automatically. Paste a full code and it is validated instead.
PNG or SVG for printing labels?
SVG for print, since it stays crisp at any size and keeps the bars sharp. PNG is fine for quick on-screen use.
Will it scan reliably?
Yes, when printed with enough size and quiet space around it, and with dark bars on a light background. Always test a print with your scanner before a big run.
Is my data sent to a server?
No. Everything runs locally in your browser. Your links, contact details, WiFi password and images never leave your device — nothing is uploaded, logged or stored.
