How to create a barcode – step-by-step guide

Creating a barcode takes only a few seconds. This guide shows which barcode type to pick, how to fill it in correctly and which format to export for print or web.

1. Choose the right barcode type

For retail products use EAN-13 or UPC, for internal marking and logistics Code 128 or Code 39, for books ISBN. For digital content, WiFi or payments use the QR code.

2. Enter a value and check the preview

Type your value (e.g. a GTIN or URL). The preview is generated instantly. For EAN/UPC, use the correct number of digits – the check digit is calculated automatically.

3. Adjust the design

Tune colors, module size and the quiet zone (border). For reliable scanning, use high contrast and a sufficient light margin.

4. Download: PNG, SVG or PDF

For web, PNG is enough. For print and scaling use SVG. For label sheets and archiving export as PDF.
