Barcode Generator

Simple CodePen Demo

Settings CodePen Demo

Supported barcodes:

Examples for browsers:

First create a canvas (or image)

<svg id="barcode"></svg>
<!-- or -->
<canvas id="barcode"></canvas>
<!-- or -->
<img id="barcode"/>

Simple example:

JsBarcode("#barcode", "Hi!");
// or with jQuery


Example with options:

JsBarcode("#barcode", "1234", {
  format: "pharmacode",
  lineColor: "#0aa",
  displayValue: false


More advanced use case:

  .options({font: "OCR-B"}) // Will affect all barcodes
  .EAN13("1234567890128", {fontSize: 18, textMargin: 0})
  .blank(20) // Create space between the barcodes
  .EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})


Or define the value and options in the HTML element:

Use any jsbarcode-* or data-* as attributes where * is any option.

<svg class="barcode"

And then initialize it with:



Retrieve the barcode values so you can render it any way you'd like

Pass in an object which will be filled with data.

const data = {};
JsBarcode(data, 'text', {...options});

data will be filled with a encodings property which has all the needed values. See wiki for an example of what data looks like.

Setup for browsers:

Step 1:

Download or get the CDN link to the script:

Name Supported barcodes Size (gzip) CDN / Download
All All the barcodes! 10.1 kB JsBarcode.all.min.js
CODE128 CODE128 (auto and force mode) 6.2 kB JsBarcode.code128.min.js
CODE39 CODE39 5.1 kB JsBarcode.code39.min.js
EAN / UPC EAN-13, EAN-8, EAN-5, EAN-2, UPC (A) 6.7 kB JsBarcode.ean-upc.min.js
ITF ITF, ITF-14 5 kB JsBarcode.itf.min.js
MSI MSI, MSI10, MSI11, MSI1010, MSI1110 5 kB JsBarcode.msi.min.js
Pharmacode Pharmacode 4.7 kB JsBarcode.pharmacode.min.js
Codabar Codabar 4.9 kB JsBarcode.codabar.min.js

Step 2:

Include the script in your code:

<script src="JsBarcode.all.min.js"></script>

Step 3:

You are done! Go generate some barcodes :smile:

Bower and npm:

You can also use Bower or npm to install and manage the library.

bower install jsbarcode --save
npm install jsbarcode --save


With canvas:

var JsBarcode = require('jsbarcode');

// Canvas v1
var Canvas = require("canvas");
// Canvas v2
var { createCanvas } = require("canvas");

// Canvas v1
var canvas = new Canvas();
// Canvas v2
var canvas = createCanvas();

JsBarcode(canvas, "Hello");

// Do what you want with the canvas
// See https://github.com/Automattic/node-canvas for more information

With svg:

const { DOMImplementation, XMLSerializer } = require('xmldom');
const xmlSerializer = new XMLSerializer();
const document = new DOMImplementation().createDocument('http://www.w3.org/1999/xhtml', 'html', null);
const svgNode = document.createElementNS('http://www.w3.org/2000/svg', 'svg');

JsBarcode(svgNode, 'test', {
    xmlDocument: document,

const svgText = xmlSerializer.serializeToString(svgNode);
