About this tool
This page opens the barcode generator preset to EAN-13, the symbology used for ISBN book barcodes — enter your 13-digit ISBN (or the first 12 digits to have the check digit computed) and download the result.
An ISBN barcode is technically a regular EAN-13: modern ISBN-13 numbers start with the prefix 978 or 979, and the final digit is the standard EAN check digit. Type the ISBN without hyphens — the hyphens are only a human-readable convention and never appear in the barcode itself.
The barcode is built locally in your browser as vector SVG, sharp enough for a back-cover print block; a PNG export is one click away for e-book listings and mockups.
Example. The twelve digits 400638133393 in EAN-13 are completed with check digit 1, so the symbol encodes 4006381333931.
Limit. EAN-13, EAN-8 and UPC-A accept only digits of the GTIN length, and a wrong final check digit is refused.
