What is Barcode Generator?
Type a value, pick a format (CODE128, CODE39, EAN13, EAN8, UPC, ITF14, MSI, or Pharmacode), and get a scannable barcode instantly. Download it as a PNG for labels, inventory, or testing a barcode scanner. Each format has its own rules for allowed length and characters, for example EAN13 needs exactly 12-13 digits. If your input doesn't fit the format you picked, the tool tells you why instead of generating a broken code. Everything runs in your browser; nothing you type is sent anywhere.
FAQ
CODE128 is the most flexible (any character, any length) and a safe default for general use. EAN13/UPC are the standards used on retail products and require an exact digit count. CODE39 is common in logistics and inventory systems.
Formats like EAN13, EAN8, and UPC are strict about digit count (EAN13 needs 12-13 digits, UPC needs 11-12). If your value doesn't match, switch format or adjust the value's length.
