Frequently Asked Questions
Which barcode format should I use for retail products?
For retail items sold in the United States and Canada, UPC-A (12 digits) is standard. For Europe, Asia, and international products, EAN-13 (13 digits) is the global standard.
What is Code 128 best for?
Code 128 is the most versatile and compact linear barcode. It supports all 128 standard ASCII characters, including letters, numbers, and symbols, making it ideal for shipping labels, inventory, and internal asset tags.
Can I print these barcodes on physical thermal label printers?
Yes! Vector SVG exports and high-resolution PNGs can be scaled to any label size without blurring or pixelation, ensuring 100% scanner readability.
Are my barcodes or product numbers uploaded to any server?
No! The entire barcode rasterization and SVG rendering executes 100% locally in your browser. 0 bytes leave your machine.
