How it works

Complete the job in three clear steps

  1. Choose the barcode standard required by the receiving system.
  2. Enter the identifier and review any calculated check digit.
  3. Download and scan-test the PNG without stretching or cropping its quiet zone.

Important

Check the result before relying on it

Scan-test generated codes before printing or distribution. A generated barcode does not register identifier ownership, and decoded external links should be checked before opening.

Questions

About this tool

Does generating a barcode register a product number?

No. Use identifiers assigned by the relevant standards body or your authorized internal system.

Which barcode should I choose?

EAN-13 and UPC-A are common in retail, Code 128 supports dense general identifiers, and Code 39 is common in some industrial workflows.
