Barcode Generator

Type the value you want to encode, pick a symbology (Code 128 works for most text and SKUs), and the barcode renders instantly as you type. Download it as an SVG or PNG and you're done — no account, no watermark, and nothing you enter ever leaves your browser.

Code 128 suits most needs — it encodes letters, numbers and symbols in a compact width. Choose UPC-A or EAN-13 only for retail products sold in stores, since those formats require valid, registered product numbers with a fixed digit count. Code 39 is common for industrial and ID labels, and ITF-14 is used on shipping cartons.

UPC-A uses 12 digits and EAN-13 uses 13, both ending in a check digit the generator calculates for you — so you can enter just the 11 or 12 real digits and let it add the last one. EAN-8 uses 8 digits and ITF-14 uses 14. If you paste a full-length number, make sure its check digit is correct, because the tool encodes exactly what you type.

Yes — a vector SVG that stays razor-sharp at any size, or a PNG rendered at 3x scale on a white background. Use the SVG when you'll resize or print at a real label size; the PNG is a fixed raster, so size it generously and check the thin bars before a full print run. Both download with one click, free.

The barcode image this tool draws is free to generate and use. But the number you encode is your responsibility: to sell through major retailers, the number inside a UPC-A or EAN-13 must be a GTIN built on a GS1 Company Prefix licensed to you (in the US, GS1 US also issues individual GTINs). This tool draws the barcode — it doesn't assign or check ownership, so don't encode a number that belongs to another company. For internal use like inventory, asset tags or event tickets, no registration is needed.

A traditional barcode is 1D — a row of lines that holds a short number or code, ideal for products and SKUs. A QR code is 2D and holds far more, like a full URL or contact card. If you need to encode a link, use a QR code generator instead; for a product or inventory code, a 1D barcode is the right tool.

For anything printed, download the SVG — it's vector, so the bars stay razor-sharp at any size and never pixelate. If you need a raster, the PNG here is rendered at about 3x; aim for 300 DPI or more at the final print size so the narrowest bar stays clean. The PNG comes on a solid white background, not transparent — that white is the contrast a scanner needs, so keep it, and don't shrink a retail code below about 80% of its standard width.

Usually it's missing quiet zones, poor contrast, or being printed too small. Keep blank margins on both sides, use black bars on white, and print large enough that the thin bars stay crisp and distinct. Test it with a barcode scanner app before committing to a full print run.
