Understanding Barcode Formats

Multiple Formats

CODE128 encodes any text or numbers, while EAN-13 and UPC-A are fixed-length numeric formats used in retail.

Retail-Ready Codes

EAN-13 and UPC-A follow the exact structure used on real product packaging worldwide.

Downloadable PNG

Save the generated barcode as a PNG, ready to print on labels or packaging.

Local Processing

The barcode is rendered entirely in your browser — your input is never sent to a server.

Choosing a Format

Use CODE128 for general-purpose labeling, inventory tracking, or asset tags since it accepts any alphanumeric text. Use EAN-13 or UPC-A only if you have an actual, valid retail product code — both formats require a specific digit count and a correct check digit, and this tool will reject invalid values for them.

Key Takeaways

Three Formats: CODE128 for general text, EAN-13 and UPC-A for standard retail product codes.
Input Validation: Invalid values for EAN-13/UPC-A are rejected with a clear error message.
Client-Side Only: All generation happens locally in your browser — no data is ever sent to a server.
