Result

This page opens the barcode generator with EAN-13 already selected — enter the 12 digits of your article number and the tool appends the correct check digit automatically, showing you which digit it added.

EAN-13 is the retail standard used on product packaging in most of the world: 12 data digits plus one check digit, encoded with L/G/R patterns whose parity hides the first digit. A wrong check digit makes the code unscannable, which is exactly what the built-in validation protects you from.

The barcode is generated locally as vector SVG with correct guard bars and quiet zones, so it stays sharp on packaging proofs. For US-style 12-digit codes, use the UPC-A format in the same tool.

Executed in Browser

Your files and inputs never leave this device. Processing runs completely offline. 100% Secure.

Accepted Formats & Rules

  • Five symbologies: Code 128 (auto subset B/C), EAN-13, EAN-8, UPC-A and Code 39.
  • Live validation of allowed characters, length and check digit while you type.
  • Human-readable digits rendered under the bars, with proper quiet zones.
  • One-click download as SVG (vector) or PNG (raster, 3x scale).

Key Benefits

✓ Runs entirely in your browser: product codes and internal SKUs are never uploaded anywhere.
✓ Automatic check digits: enter 12 digits for EAN-13 and the tool computes and appends the 13th, telling you which digit it added.
✓ Vector output: the barcode is built as SVG rectangles, so it prints razor-sharp at any size — PNG export included for quick pasting.

Use Cases

  • • Print EAN-13 or UPC-A labels for products going to retail — enter the 12 (or 11) digits and let the tool compute and verify the check digit.
  • • Generate Code 128 barcodes for warehouse bins, asset tags and shipping paperwork that scanners must read reliably.
  • • Put an ISBN barcode (EAN-13 with the 978/979 prefix) on a book cover as crisp vector SVG that survives any print size.
