Barcode Generator
Build a 1D barcode from any text or numeric value and download it as a high-resolution PNG, ready for shipping labels, inventory tags, event tickets, retail SKUs, or product packaging. Supports CODE128 (the everyday workhorse — handles any ASCII), EAN-13 (retail), EAN-8, UPC-A (US retail), CODE39 (industrial / military), ITF-14 (cartons), MSI (warehouse), pharmacode (pharmaceutical), and codabar (libraries, blood banks). Customise bar width, height, foreground and background colours, and whether the value is printed underneath. Rendering happens entirely in your browser via JsBarcode — no upload.
