Barcode generator (Code 128, EAN-13, UPC)
Generate Code 128, EAN-13, EAN-8, UPC-A, Code 39 and ITF-14 barcodes as scalable SVG.
Input
Result
The result will appear here.Labels for a small warehouse, an asset tag for an office laptop, a mock-up of a retail pack, a test fixture for a scanner integration. This draws one-dimensional barcodes with JsBarcode as SVG, a vector format that prints crisp at any size and drops into Illustrator, Figma or a label template. For the retail symbologies the check digit is computed for you, and a wrong one is caught along with the digit it should have been.
How it works
- Code 128 takes any printable ASCII and is the default for internal labels; Code 39 is limited to capitals, digits and a few symbols but is still required by some older systems.
- EAN-13, EAN-8, UPC-A and ITF-14 take their data digits and get the GS1 mod-10 check digit appended; if you type the full number, the check digit is verified instead.
- Bar width sets the narrowest bar in pixels (the X-dimension) and bar height the length of the bars; the human-readable text under them can be switched off.

Common questions
- Can I make a real EAN-13 for a product I sell?
- You can draw one for any number, but a barcode that retailers accept needs a number assigned to your company by GS1 (in China, the Article Numbering Center of China). Made-up numbers scan fine but may clash with a real product in a shop's system.
- Why can't I put Chinese text in a barcode?
- The 1D symbologies here encode only digits or ASCII characters. For Chinese text, a URL or anything long, use a QR code, which stores UTF-8 and holds kilobytes instead of a few dozen characters.
- How big should I print it?
- Scanners need the narrowest bar to be at least about 0.25 mm wide for Code 128 and around 0.33 mm for EAN-13 at its nominal size, plus a clear margin on both sides. Because the output is SVG, scale it in your layout tool rather than stretching a bitmap.
The open-source behind it
This tool runs on lindell/JsBarcode, released under MIT. If you need the same behaviour inside your own program, that is the library to reach for.
