Barcode Generator

A linear barcode encodes data as bars of varying width, read by a single laser beam in a scanner. Unlike a QR code, most formats are limited to digits or ASCII text, but in exchange they're readable by virtually any retail scanner.

How to use it

• Pick a format (CODE128, EAN-13, UPC, CODE39, and more) and enter text or digits — the barcode is generated instantly.
• For fixed-length formats (EAN-13, UPC-A), the check digit is calculated automatically.
• Download the finished image to print on a label or paste into a document.

Common uses

• Creating a barcode for a homemade product or internal warehouse inventory.
• Printing test barcodes to check a scanner or POS system before going live.
• Generating CODE128 for internal identifiers (order numbers, batch numbers) that don't need to meet a strict retail standard.

Things to keep in mind

EAN-13 and UPC-A are official retail standards — selling a product in stores requires a real, registered GTIN, not an arbitrarily generated one.

No common linear barcode format supports non-Latin scripts or other Unicode characters directly — use a QR code for that kind of text.
