About the EAN-13 Barcode Generator

Type twelve digits and the check digit is added, or thirteen and it is verified. EAN-13 is the retail barcode outside North America; print it at 80 to 200 percent of its nominal 37.29 × 25.93 mm.

Frequently asked questions

What size should an EAN-13 be?
The nominal size is 37.29 mm wide by 25.93 mm high; GS1 allows 80% to 200% of it. Smaller codes need a better printer.
Is anything I type or scan uploaded?
No. Codes are drawn and read inside your browser (bwip-js and the ZXing reader, compiled to WebAssembly); nothing you type, upload or point the camera at reaches our servers.
Can I make codes from a script, a spreadsheet or an AI agent?
Yes, with no account. https://openvibe.tools/api/codes/qrcode.svg?text=Hello is the image itself (any symbology, .svg or .png; /api/codes lists them), so it works in an <img> tag or Markdown. POST /api/v1/tools/<tool>/run answers JSON, and the OpenAPI document is at https://openvibe.tools/api/v1/openapi.json.
