Frequently asked questions

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 for retail products. Code 39 is an older format supported by older scanners. ITF-14 is used for shipping containers and outer 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 automatically. UPC-A requires 12 numeric digits.
Can I change barcode colours?
Yes. You can set custom foreground and background colours using the colour pickers. Ensure sufficient contrast between the two colours for reliable scanning.
What resolution is the downloaded PNG?
The output resolution depends on the scale setting. Higher scale values produce larger images suitable for print use.
