Barcode Generator
Generate an EAN-13, EAN-8, UPC-A or ITF barcode from a number, with a live preview, an automatically calculated check digit, and PNG or SVG download.
Available formats
Pick the format as an option within this same tool — they're not separate pages, since generating any of them is the same mechanism with a different encoding table.
| Format | Common use | Digits |
|---|---|---|
| EAN-13 | Retail products in Europe/most of the world | 12 (+ 1 check digit) |
| EAN-8 | Small products with no room for a full EAN-13 | 7 (+ 1 check digit) |
| UPC-A | Retail products in the US/Canada | 11 (+ 1 check digit) |
| ITF | Shipping and logistics cartons (Interleaved 2 of 5) | any even count |
The check digit
If you type the number without its last digit (e.g. 12 digits for EAN-13), it's calculated automatically using the standard GS1 algorithm. If you type the full number, the last digit is verified — an incorrect check digit is never accepted or invented.
Privacy
The barcode is generated entirely in your browser. Whatever value you type is never sent to Numelto.
