This free barcode generator creates industry-standard barcodes directly in your browser. No data is sent to any server — everything is processed client-side using the JsBarcode library. Perfect for prototyping, testing, and small-run label printing.
Use EAN-13 or UPC-A for retail products sold in stores. Use Code 128 for general-purpose alphanumeric data (serial numbers, URLs, internal codes). Use ITF-14 for shipping cartons. Code 39 works well for industrial and automotive environments.
Yes — completely free, no account required, no watermarks on downloads. The tool runs entirely in your browser, so your data never leaves your device.
Absolutely. Download as SVG for lossless vector printing at any scale, or as PNG for use in documents and web pages. SVG is recommended for professional printing.
EAN-13 is an international standard (ISO/IEC 15420) that encodes exactly 12 data digits plus a check digit, totaling 13. The check digit is calculated automatically — just enter your 12-digit data and the barcode will include the correct check digit.
Yes. Use the Bar Color and Background controls to set any color. However, for reliable scanning, maintain strong contrast — dark bars on a light background. Avoid red bars as many laser scanners cannot read them.
Yes, when generated with valid data for the chosen format. The barcodes follow official specifications and should scan correctly with any standard barcode reader. Always test with your actual scanner before mass printing.
Creating professional barcodes has never been simpler. Our free barcode generator supports all major 1D barcode formats used in retail, logistics, healthcare, and manufacturing. Whether you need a single barcode for a prototype or want to quickly test a product label, this tool delivers print-ready output in seconds — entirely within your browser.
Code 128 is the most versatile 1D barcode format available. It encodes the full ASCII character set including numbers, uppercase and lowercase letters, and special characters, making it the go-to choice for internal serial numbers, shipping labels, and applications where data flexibility matters.
EAN-13 (European Article Number) is the global standard for retail product identification used in virtually every country outside North America. It encodes 12 data digits plus a calculated check digit. Every product sold in supermarkets and retail stores worldwide carries an EAN-13 or equivalent barcode.
UPC-A is the North American equivalent of EAN-13, encoding 11 data digits plus a check digit for a total of 12. It is the standard for retail products sold in the United States and Canada and is compatible with any EAN/UPC scanner.
EAN-8 is a compact version of EAN-13 designed for small products where space is limited. It encodes 7 data digits plus a check digit. Common applications include small bottles, tubes, and confectionery.
Code 39 (also known as 3 of 9) is one of the oldest and most widely used barcode formats in non-retail environments. It supports uppercase letters, digits 0–9, and a handful of special characters. It is the standard in the U.S. Department of Defense and automotive industries.
ITF-14 (Interleaved 2 of 5) encodes 14-digit GTIN numbers and is used on shipping cartons and outer packaging. It is designed to be printed directly on corrugated cardboard and is readable even on low-quality print surfaces.
MSI Plessey is a barcode format derived from the original Plessey code, primarily used for inventory control in retail shelf labeling and warehouse management systems.
Pharmacode (Pharmaceutical Binary Code) is a specialized barcode used exclusively in the pharmaceutical and cosmetic industries for packaging verification. It encodes numeric values from 3 to 131070.
When downloading your barcode, you have the choice between PNG and SVG. SVG (Scalable Vector Graphics) is the preferred format for any professional printing application. Because SVG is a vector format, it can be scaled to any size — from a tiny label to a large banner — without any loss of quality. Print shops and graphic designers strongly prefer SVG for barcode work.
PNG is a raster image format best suited for digital use: embedding in Word documents, PDFs, email signatures, or website product pages. When using PNG for print, ensure you generate it at a high enough resolution (high bar height and width settings help) for your target print size.
This tool uses the open-source JsBarcode library, a well-maintained JavaScript library that implements barcode generation to official standards. All processing happens client-side in your browser — no data is transmitted to our servers, making this tool safe for use with sensitive internal codes, part numbers, and proprietary data.
Designers can customize bar color and background independently, allowing barcodes to match brand colors for packaging mockups and concept art. Remember that unconventional colors may not scan reliably in production — always revert to high-contrast black/white for final production artwork.
For developers needing to generate barcodes programmatically in bulk quantities, consider integrating a server-side library such as picqer/php-barcode-generator for PHP projects, or using JsBarcode directly in your Node.js or browser-based application.
