Frequently Asked Questions (FAQ)

Q1. Are barcodes generated by this tool valid for retail use?
A1. If you select a standard type like EAN-13 or UPC-A and ensure your data follows the standard format (correct number length, country code, check digit), yes. For commercial space always verify with your retailer/partner.

Q2. Do I need special software to use the generated barcode?
No — the downloaded image (PNG, SVG, PDF) can be used in packaging design, websites or print. Just use a normal image editor or embed directly.

Q3. What’s the difference between barcode types (e.g., EAN-13 vs Code128)?
EAN-13 and UPC-A are standards for retail products. Code 128 is a high-density linear barcode for alphanumeric data. QR Code is 2-D barcode for URLs. Choose depending on use.

Q4. Can I customise the barcode size or colour?
Yes — many generators allow custom size or file format. For colour, ensure scan-compatibility (dark bars on a light background are best).

Q5. Is this tool free and secure?
Yes — you don’t need to sign up and the barcode is generated instantly in the browser. No need to worry about data storage unless you upload sensitive information.
