1D Barcode Generator
Generate high-quality 1D barcodes instantly in your browser. Whether you need standard retail barcodes like EAN and UPC, or robust industrial formats like CODE128 and CODE39, this tool generates them strictly client-side without sending your data anywhere.
Supported formats
- CODE128: High-density alphanumeric format used widely in logistics and inventory.
- EAN / UPC: The global retail standards (EAN-13, EAN-8, UPC-A, UPC-E) required for point-of-sale scanning.
- CODE39 / ITF-14: Classic industrial and shipping container formats.
Customization and export
You can adjust the barcode’s structural properties (bar width and height) and visual aesthetic (line color, background color, and text visibility). The preview updates instantly. When ready, export the result as an SVG vector for lossless printing, or a standard PNG image.
