What This Tool Does

How to Use
1. Select a barcode format from the dropdown.
2. Enter the value to encode in the text field — the barcode updates automatically.
3. Adjust width, height, and colours as needed.
4. Click PNG or SVG to download.
Frequently Asked Questions
Which barcode format should I use?
Code128 supports all ASCII characters and any length — use it for internal labels, shipping, and general purposes. EAN-13 and UPC-A are retail standards for product barcodes (requiring a registered GS1 prefix). Code39 is used in automotive and defence industries. ITF (Interleaved 2 of 5) is used for cartons and logistics. EAN-8 is a shortened EAN for small products.
Can I use this for retail product barcodes?
You can generate EAN-13 and UPC-A barcodes here, but to sell products in retail stores you need a registered GS1 company prefix and legitimate product numbers. Self-assigned EAN/UPC numbers are not valid for retail without GS1 registration.
What is the difference between PNG and SVG download?
PNG is a raster image — suitable for printing at a fixed size. SVG is a vector format that scales to any size without quality loss, making it ideal for professional print work, labels, and any use where the barcode will be printed at varying sizes.
Is my data sent to a server?
No. Barcodes are generated entirely in your browser using the JsBarcode library. Nothing is transmitted to our servers.
