Frequently Asked Questions
Select a barcode type, enter your numeric value and click Generate Barcode. A barcode SVG appears in the preview panel and you can download it as SVG or PNG for printing or documentation.
The generator supports EAN-13, EAN-8, UPC-A and Code 128. EAN and UPC are commonly used for retail products, while Code 128 is flexible for internal codes, shipping labels and inventory systems.
Yes. If you enter one digit fewer than the full length (for example 12 digits for EAN-13 or 11 digits for UPC-A), the generator calculates the final check digit automatically before rendering the barcode.
The generator is 100% free to use and does not add any watermark or branding to the barcode image. You are responsible for using valid product numbers assigned by your barcode provider.
Technically yes—the barcodes are standards-compliant images—but you still need properly licensed product numbers from an authority such as GS1 or from your retailer. This tool only draws the barcode image from the code you provide.
No. Barcode generation runs entirely inside your browser using JavaScript and the JsBarcode library. The numbers you enter are not transmitted or stored on a remote server.
Most scanning issues come from printing the barcode too small, using low contrast, or placing it on a curved surface. Try increasing the bar height and width, use dark ink on a light background and ensure your printer resolution is adequate.
EAN and UPC codes must be numeric only. If you need letters or a mix of characters, choose Code 128 from the barcode type menu, which supports alphanumeric data and many special characters.
