Barcode Generator

CODE128, almost every time. It encodes the full ASCII set, packs digits densely, and carries no registration requirement, so SKUs like WH-A3-0091 work as-is. Your scanner hardware almost certainly reads it out of the box.

EAN-13 expects exactly 12 digits, after which the check digit is calculated and appended for you. Letters, spaces, or a wrong digit count trigger the red error alert instead of rendering. Paste digits only and the preview comes back.

Yes. Enter the first 12 digits and the thirteenth is computed by the standard modulo 10 algorithm. Typing 590123412345 renders the complete number 5901234123457 under the bars, ready for packaging artwork.

UPC-A is 12 digits and rooted in North American retail; EAN-13 is 13 digits and used nearly everywhere else. EAN-13 is effectively a superset, since a UPC-A number with a leading zero reads as valid EAN-13. Modern scanners handle both without configuration.

The image itself is standards compliant, but retail requires the number inside it to be assigned through GS1, which licenses unique company prefixes. For anything scanned only inside your own building, no registration is needed and any numbering scheme you invent is fine.

For barcodes specifically, yes. Scanners measure the precise widths of bars and gaps, and rasterized images blur those edges when scaled. An SVG keeps the geometry exact at any print size, which is why this tool outputs vectors only.

CODE39 survives in older industrial and government systems that were built around it, though it encodes less per inch than Code 128. ITF14 is the standard for outer shipping cartons, where its fault tolerance suits corrugated cardboard printing.

It's a free barcode generator, but it renders one code per value rather than importing a spreadsheet, so it isn't a true batch tool. For a short list you can still treat it as a free bulk barcode generator by typing each value, downloading the SVG, and repeating; there's no cap and no signup.

Yes, in the sense that it runs entirely in your browser with nothing to install, which is what people want from a bulk barcode generator online. Just know each barcode is generated one at a time here, so a run of fifty means fifty quick rounds rather than one upload.

Everything is free with no daily limit, so as a bulk barcode generator online free workflow you can make as many as you have patience for. There's no batch import, though; the honest description is unlimited single codes rather than one-click bulk.

Not simultaneously; you pick one format from the dropdown per render. As a free multiple barcode generator it handles many codes across a session, switching between CODE128, EAN13, UPC, and the rest between each one. Searches like bulk barcode generator free online barcode really describe this one-at-a-time flow.

Yes, choose EAN13 or UPC and enter the digits your product carries; the product barcode generator online computes the check digit and renders print-ready SVG. Remember the number itself must come from GS1 if the item will be scanned in real stores.

That's its strongest use. As a free barcode maker for inventory, CODE128 encodes your own SKUs like WH-A3-0091 with no registration needed, since nothing leaves your building. Print the SVG onto label stock and your scanner reads it right away.

Enter the value, pick the format, and click Download SVG; vector output is what lets you create retail barcode labels that stay crisp at any label size. Drop the SVG into your label template, set the physical width, and the bars keep their exact proportions.

It's built to be. As an easy barcode generator it defaults to CODE128, shows a live preview, and flags a red error the moment a value breaks a format's rules, so you can't accidentally print something unscannable. Type, check, download.
