Generate EAN-13 or Code-128 barcodes for free
Whether you're labeling retail products for a shop shelf or an e-commerce listing, or just need a scannable code for internal inventory, this tool generates a print-ready barcode instantly — no design software, no login, and no watermark. Choose EAN-13 for standard retail products (the kind found on nearly every packaged item you buy) or Code-128 for any alphanumeric value like a SKU, batch code, or internal reference number.
Type your value, pick a type, and the barcode renders instantly, ready to download as a PNG or a scalable SVG. Nothing you type is ever sent to a server — the barcode is generated entirely inside your browser using JavaScript.
EAN-13: the check digit, handled for you
An EAN-13 barcode encodes 13 digits, but the 13th is a check digit calculated from the other 12 using a fixed formula — get it wrong and the barcode either fails to scan or scans as the wrong product. Type just the 12 digits and this tool computes the correct 13th digit automatically; type all 13 and it verifies the check digit you entered is correct, flagging it clearly if it isn't. Any input that isn't exactly 12 or 13 digits, or contains a non-digit character, is rejected with a clear inline error before you waste time printing an invalid code.
A print-ready strip sheet
Set how many copies you need and use "Print Strip Sheet" to print a page of repeated barcodes at once — handy for labeling a batch of the same product without printing one at a time. Always test-scan a printed barcode with a real scanner or a barcode-scanning phone app before relying on a full print run, especially for retail products going through a POS system.
Small manufacturers, importers, and home-based sellers often need an EAN-13 barcode before they can list a product on a marketplace or a retail POS system, and getting the check digit wrong is one of the most common (and most avoidable) reasons a newly generated barcode gets rejected or scans as the wrong item. Letting this tool compute or verify that digit for you removes that entire category of mistake. For non-retail use — asset tags, internal document routing, workshop job cards, warehouse bin labels — Code-128 is usually the better fit since it accepts letters and punctuation, not just digits.
Download the SVG version if you're sending the barcode to a professional label printer or embedding it in a larger print design, since it scales to any size without losing sharpness; the PNG works fine for quick digital use or a home/office printer.
Frequently Asked Questions
It is calculated from the first 12 digits using the standard GS1 formula (odd positions ×1, even positions ×3, summed, then subtracted from the next multiple of 10). Enter 12 digits and this tool computes it for you automatically; enter all 13 and it verifies the check digit is correct.
You get a clear inline error explaining the problem — wrong digit count (not 12 or 13), a non-digit character, or (for a 13-digit entry) a check digit that does not match what the first 12 digits compute to.
Use Code-128 for any alphanumeric value that is not a standard 13-digit retail product code — SKUs, batch numbers, internal reference codes, coupon codes, and similar values all work with Code-128.
No. The barcode is generated entirely in your browser using client-side JavaScript — nothing you type here is ever uploaded.
Yes — set the number of copies and use "Print Strip Sheet" to print a full page of repeated barcodes in one go.
