How to make a barcode in 3 steps
- Choose the format. Use EAN-13 for a 13-digit retail number, UPC-A for a 12-digit North American retail number, or Code 128 for a SKU, bin, or serial.
- Enter the value. For EAN-13 and UPC-A, the check digit is added or checked before the bars are drawn. Code 128 keeps the text you type.
- Download and proof. Download PNG or SVG. Scan a printed sample with the scanner that will read it. A 2px module is a screen preview; 3px or 4px is a better start for a label.
Which format to choose
| Format | Use it when |
|---|---|
| EAN-13 | A 13-digit retail number (GTIN-13), including an ISBN-13. |
| UPC-A | A 12-digit retail number for packaging sold in the United States or Canada. |
| Code 128 | A SKU, bin, serial, or other short identifier that includes letters. |
| Scanely QR | A phone should open a page. Put it beside the barcode on the package when you need a link you can change after printing, plus scan counts. |
Pick the symbol your scanner already reads
EAN-13, UPC-A, and Code 128 are not interchangeable. A retail checkout expects a GTIN in the right length. A warehouse scanner often expects Code 128 for a SKU or location. Choose the format the receiving system was built for, then test a print with that scanner.

What this page does
The bars are drawn on this page. You can change the module width, the colors, and whether the digits print under the bars. PNG is a flat image. SVG stays sharp when a designer places it in a larger layout. Leave a blank margin around the bars; that quiet zone is included in the file.
The sample values are examples so the page is not empty. Replace them with a number or identifier you are allowed to print. Drawing a barcode does not assign that number to you.
When a QR code is the better fit
Use a barcode when a system already looks up an EAN, UPC, or Code 128 value. Use a QR code when a phone should open a link. On a package, print both: the barcode for the checkout or the warehouse, and a Scanely QR beside it for a page you can change after the carton is printed. A dynamic QR code keeps that print while the destination changes, and Scanely counts the scans. The inventory label guide separates identifying an item from updating its quantity.
