Free Barcode Generator — EAN, UPC & Code 128

A barcode generator turns text or numbers into a barcode — a pattern of black bars and spaces that a scanner can read. Type your text or product number, pick a barcode type (EAN-13, UPC-A, Code 128 or Code 39), and this free barcode generator draws the barcode instantly in your browser. You can download it as a PNG or SVG and print it on a label, a product or a document.

Use EAN-13 for products sold in shops outside North America (13 digits, the number on most products worldwide). Use UPC-A for products sold in the USA and Canada (12 digits). Use Code 128 for anything else — labels, inventory, tracking and shipping — because it can hold any letters and numbers. Use Code 39 for simple labels with capital letters, numbers and a few symbols. The full comparison is on our barcode types guide.

Yes. Barcode Generator is 100% free. There is no account, no sign-up, no limit and no fee — create as many barcodes as you like, on any device. Your text never leaves your browser.

An EAN-13 number has exactly 13 digits, and the last digit is a check digit worked out from the first 12. This generator checks it for you: for example, 5901234123457 is valid (its check digit is 7), but 5901234123458 is refused, because the correct check digit for those first 12 digits is 7, not 8. A number with only 12 digits is refused too — EAN-13 always needs 13 digits.

A UPC-A number has exactly 12 digits, and the last digit is a check digit worked out from the first 11. For example, 036000291452 is valid (its check digit is 2). If the check digit is wrong, or the number is not 12 digits long, the generator refuses it and tells you why, so you never print a barcode that will not scan.

Code 39 holds capital letters A to Z, numbers 0 to 9, a space, and the symbols - . $ / + %. Lowercase letters are changed to capitals automatically — type hello-123 and you get HELLO-123. Any other character, such as ! or @, is refused with a clear message, because Code 39 cannot encode it.

Yes — every barcode type has Download PNG and Download SVG buttons. PNG is best for printing on labels and documents; SVG stays sharp at any size and is best for design work and print shops. Both files are made in your browser, and the download is a real file, not a screenshot.

The barcode is a standard encoding of the text or number you typed, drawn to the usual proportions. Before printing hundreds of labels, test one printed copy with a real scanner or a phone barcode-scanner app. Small sizes, low printer quality and glossy paper can all make a barcode hard to read, even when the encoding is correct.
