Select your barcode format (Code 128, EAN-13, UPC-A, etc.) from the dropdown. Enter the data you want to encode — a number, product code, or text depending on the format. Click Generate and download your barcode as SVG or PNG, ready for print or digital use.
Supported formats include Code 128 (general-purpose, alphanumeric), Code 39 (legacy systems), EAN-13 (retail products worldwide), EAN-8 (small packages), UPC-A (US retail), UPC-E (compact UPC), and ITF-14 (shipping containers). Choose the format based on your industry or system requirements.
Traditional barcodes are one-dimensional (1D) — they encode data in horizontal bars and can typically store 10–40 characters. QR codes are two-dimensional (2D) and can store up to 3,000 characters including URLs, contact info, and more. Use barcodes for product SKUs and inventory; use QR codes for richer data and mobile scanning.
Code 128 supports the full ASCII character set — letters, numbers, and symbols. It is the most flexible 1D barcode format and is widely used for shipping labels, inventory management, library systems, and internal tracking codes. There is no strict length limit, though shorter codes scan more reliably.
Enter your 12-digit product code (the 13th digit is a calculated check digit). Select EAN-13 as the format and click Generate. The tool automatically computes the check digit and generates a print-ready barcode. For official retail use, EAN-13 numbers must be officially registered through GS1.
Yes. Download as SVG for the best print quality — SVG is vector-based and scales to any size without pixelation. PNG is suitable for screen display and lower-resolution printing. For retail labels, aim for a minimum barcode width of 3 cm for reliable scanning.
Barcodes generated using the correct format and valid data will scan with any standard laser or CCD barcode scanner used in retail, warehousing, and logistics. Always test scan a generated barcode with your specific scanner before mass printing.
No. Barcode generation happens entirely in your browser using JavaScript. Your product codes, inventory numbers, and other data are never transmitted to any server or logged by our system.
