Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
What barcode formats can I generate?
You can generate standard CODE128, EAN-13, and UPC-A barcodes. Please ensure you enter valid digit structures for EAN (13 digits) and UPC (12 digits).
Can I customize the print sheet layout?
Yes, you can choose between a single product label or print-ready Avery A4 layouts with 24 (3x8 grid) or 40 (4x10 grid) labels per page.
What is the difference between CODE128, EAN-13, and UPC-A barcodes?
CODE128 is a flexible format that can encode letters, numbers, and symbols, commonly used for shipping and inventory. EAN-13 is the standard 13-digit barcode used for retail products in Europe and most of the world. UPC-A is the 12-digit equivalent primarily used for retail products in the US and Canada.
Will the barcode I generate work with real scanners and POS systems?
Yes. Barcodes are generated to standard specifications, so they scan correctly with handheld scanners, smartphone scanner apps, and point-of-sale (POS) systems, as long as the digit structure for EAN-13 or UPC-A is valid.
Is this barcode generator free to use, and are there any limits?
Yes, the tool is completely free with no daily generation limits or watermarks. Since everything runs locally in your browser, there's also no signup required.
Can I generate a barcode from a product's existing EAN or UPC number?
Yes, simply enter your existing EAN-13 (13-digit) or UPC-A (12-digit) number into the input field, and the tool will generate a scannable barcode image matching that exact code.
What image format does the generated barcode download as?
Barcodes can be downloaded as high-resolution PNG images, suitable for printing on product packaging, shipping labels, or inventory tags.
Why is my barcode showing as invalid or not generating?
This usually happens when the digit count doesn't match the format — EAN-13 requires exactly 13 digits and UPC-A requires exactly 12 digits. Double-check for extra spaces or missing digits and try again.
Can I generate multiple barcodes at once for a product catalog?
Currently, barcodes are generated one at a time, but you can quickly regenerate and download barcodes individually for each product before arranging them in your chosen Avery label layout.
Are barcodes generated here uploaded to any server?
No. Barcode generation happens entirely in your browser using local processing — your product codes and data are never uploaded or stored on any server, keeping your inventory information private.
