Frequently Asked Questions
Which barcode format should I choose?
CODE128 works for general text and numbers. EAN-13 is the retail standard for products sold in stores. UPC-A is the US retail equivalent. CODE39 is common for industrial labels.
What is the difference between EAN-13 and UPC-A?
Both encode product numbers for retail. EAN-13 holds 13 digits and is used worldwide; UPC-A holds 12 digits and is standard in North America.
How do I download the barcode?
Press “Download PNG” after generating. The image is high-contrast black on white, suitable for printing on labels.
Will these barcodes scan with a real scanner?
Yes, as long as the value is valid for the chosen format (for example, EAN-13 needs exactly 12–13 digits) and it is printed at a reasonable size with good contrast.
Is my data uploaded anywhere?
No. Barcodes are rendered entirely in your browser — the value you enter never leaves your device.
