Barcode Generator FAQ

Which barcode type should I use?
Code 128 is the most versatile — it supports all ASCII characters and is widely used in logistics and general labelling. EAN-13 and UPC-A are standard for retail products. Code 39 is an older format supported by legacy scanners. ITF-14 is used for shipping containers and outer carton packaging.

What input format does EAN-13 require?
EAN-13 requires exactly 13 numeric digits. The last digit is a check digit — if you enter 12 digits, the check digit is calculated and appended automatically. UPC-A requires 12 numeric digits.

Can I change barcode colors?
Yes. Set custom foreground and background colors using the color pickers. Ensure sufficient contrast between the two — insufficient contrast will prevent scanners from reading the barcode reliably.

What resolution is the downloaded PNG?
Output resolution depends on the scale setting. Use a higher scale value to produce larger images suitable for print. A scale of 3–4 works well for most label printing applications.

Is Code 128 suitable for retail products?
Code 128 is used in many retail and logistics contexts but is not the GS1-standard retail code. For products sold in retail stores, EAN-13 (Europe) or UPC-A (North America) are the required standards.

Is my data sent to a server?
No. All barcode generation happens locally in your browser. Your product codes, serial numbers, and data are never transmitted to any server.

Can I use this for shipping labels?
Yes. Code 128 and ITF-14 are both commonly used on shipping labels. Generate at a high scale and download PNG for import into label design software.

What is ITF-14?
ITF-14 (Interleaved 2 of 5, 14 digits) is a GS1 barcode format used on outer cartons and shipping containers. It encodes a 14-digit GTIN. The thicker bars make it scannable even on corrugated cardboard surfaces.

Does it work on mobile?
Yes. The generator is fully responsive and works in any modern mobile browser. You can generate and download barcodes directly on your phone or tablet.
