About barcodes
A barcode generator creates standard barcodes from your text or numbers — CODE128, EAN-13, UPC-A and more. Enter the value, choose the barcode type, and download the image for labels, products, inventory and tickets. It runs entirely in your browser and produces crisp, scannable barcodes.
How Barcode works
How to generate a barcode
- Enter the text or number to encode.
- Choose a barcode type (CODE128, EAN-13, UPC-A and others).
- Download the barcode image to print on labels or products.
Choosing a type
CODE128 handles letters and numbers and is great for general use; EAN-13 and UPC-A are retail product codes with fixed digit lengths. Pick the type your scanner or system expects.
Print clear, scannable codes
Download at a high resolution and keep a quiet (blank) margin around the barcode so scanners read it reliably.
