A barcode generator is an online tool that converts text or numbers into scannable barcodes. It supports multiple barcode formats (UPC, Code128, EAN, Codabar) and outputs high-resolution images suitable for labels, packaging, or digital use. The generated barcodes follow international standards and are compatible with all common barcode readers.
Enter your data (product number, SKU, order ID, or any text), select your barcode format, and the tool encodes it into a visual pattern of bars and spaces. Each format has specific rules: UPC-A requires 12 digits and is standard for retail; Code128 handles any text and is common in logistics; EAN-13 is used internationally. The tool then renders the encoded data as a high-resolution image that scanners read by detecting bar widths and spacing.
| Input | Result | Notes |
|---|---|---|
| Product SKU: 5901234123457, Format: EAN-13 | A barcode image with alternating black and white bars representing the 13-digit code | EAN-13 is standard for retail products in Europe and internationally; easy for store checkouts |
| Order ID: ORD-2024-8472-X, Format: Code128 | A barcode that encodes letters, numbers, and special characters | Code128 works for mixed alphanumeric data, ideal for shipping and warehouse tracking |
| Inventory Code: A2-B7-C3, Format: Codabar | A compact barcode using bars of four widths | Codabar is compact and reads quickly; used in libraries and blood banks |
The tool typically supports UPC-A (retail in North America, 12 digits), EAN-13 (retail internationally, 13 digits), Code128 (logistics and flexible data, any length), Code39, and Codabar. Each format has different use cases and data capacity.
Yes. For e-commerce, use Code128. For retail shelves, use UPC-A or EAN-13 (you may need to register with GS1 for official retail barcodes). For internal inventory tracking, any format works fine.
PNG is a raster image that looks good at its original size but pixelates if enlarged; SVG is vector-based and scales infinitely without loss. Use SVG for printing at various sizes, PNG for web and label printing at a fixed size.
Standard barcodes follow internationally recognised formats, so they work with any standard barcode reader (supermarket scanners, warehouse handheld devices, smartphone apps). Always test before relying on it in production.
This tool generates one barcode at a time, but you can repeat the process quickly. For bulk generation, you might use a spreadsheet or scripting tool that calls the API if available, or use a dedicated inventory system.
No—this is a free tool with no limits. Generate as many as you need for your business, labels, or projects.
