Barcode generator
for labels and codes.

Create common linear and two-dimensional symbols, then export as PNG or SVG. Generation runs on your device.

For products sold at retail, use a legitimate GS1-issued product identifier. This tool creates a symbol from the value you provide; it does not issue or validate ownership of a GTIN.

PREVIEW CODE 128
Enter a supported value to preview

Scan a test print with the device and workflow that will use this symbol.

Select the format your scanner expects

Code 128 and Code 39 are used for general alphanumeric labels; ITF encodes paired digits. EAN and UPC are retail symbol formats, while Data Matrix, PDF417 and Aztec are two-dimensional symbologies. The system that will scan your output determines which format and content are accepted.

EAN and UPC identifiers

This tool calculates check digits for EAN-13, EAN-8 and UPC-A from the entered base digits. It does not issue a GS1 GTIN or verify that the number is licensed to you. For retail products, obtain and use the identifier required by GS1, your marketplace and your retailer. UPC-E is not offered yet because its output has not passed the independent readback check used for the other formats.

Verify a test print

Use the target device or workflow to scan the downloaded output at the final size. Check the quiet space around the bars or symbol, contrast, print quality, and any minimum-size rules from your label or retail specification. A successful digital preview does not guarantee compliance with a retail standard.

Common questions

Does generating a retail barcode assign me a product identifier?

No. This tool renders a symbol from the data you provide. Obtain retail GTINs through the appropriate issuing organization.

Are the check digits included?

The EAN-13, EAN-8 and UPC-A encoders add a check digit to the base digits you enter. The other supported formats use their own format rules.

For identifier background, see EAN vs UPC and the printing guide.
