Frequently Asked Questions
- Which barcode format should I use?
- CODE128 is the best general-purpose choice — it encodes any ASCII text compactly. EAN13/EAN8 and UPC are retail standards that require numeric digits with a valid check digit.
- Why is my EAN13 barcode invalid?
- EAN13 requires exactly 12 digits (the 13th is a computed check digit). If you supply the wrong length or non-numeric characters, the barcode cannot be generated.
- Can I use the generated barcodes commercially?
- Yes — barcodes generated here carry no watermark or license restriction. Note that officially registered retail codes (GTIN/EAN) must be obtained from GS1.
- What resolution is the downloaded PNG?
- The PNG is rendered at the on-screen resolution of the preview. For print use, generate at a larger size to ensure scanners can read it reliably.
