Acerca de esta herramienta
Type a value and get a scannable barcode instantly. Pick EAN-13 or UPC-A for retail products, Code 128 for shipping labels and inventory, Code 39 for IDs and industry, and ITF-14 for cartons.
Bulk barcodes for labels
Switch to bulk mode, paste one value per line (SKUs, serial numbers, asset tags) and download up to 500 barcodes as a ZIP of PNG or SVG files, numbered in order.
Print-ready quality
SVG files are vector graphics, so they stay razor-sharp at any label size. Keep dark bars on a light background and leave the quiet zone (margin) around the code so every scanner reads it.
Note: to sell in retail stores you need officially assigned product numbers (from GS1); this tool draws the barcode for the number you enter. Everything runs in your browser: nothing is uploaded, stored or tracked.

Preguntas frecuentes
Are these barcodes free to use commercially?
Yes. The images you create are yours to use on products, labels and documents. For retail EAN/UPC codes, the number itself must be registered with GS1.
Which barcode type should I choose?
EAN-13 (worldwide) or UPC-A (US/Canada) for retail products, Code 128 for shipping and inventory labels, Code 39 for IDs and badges, ITF-14 for outer cartons.
Why does it say my number is invalid?
EAN and UPC have a fixed length and a check digit. Enter 12 digits for EAN-13 (or 11 for UPC-A) and the check digit is added for you; a wrong 13th digit is rejected.
Can I print them?
Yes. Download SVG for printing: it stays sharp at any size. PNG is exported at 3× resolution for screens and documents.
