What is the difference between EAN-13, UPC-A, and Code 128?

EAN-13 (13 digits) is the international standard for retail point-of-sale products worldwide. UPC-A (12 digits) is the primary North American barcode. Code 128 is a versatile high-density format that encodes numbers, letters, and symbols for logistics and warehouse management.

How is the check digit calculated?

Our tool automatically computes the official Modulo-10 checksum (with alternating 1 and 3 weights) for EAN-13, EAN-8, UPC-A, ISBN-13, and ITF-14. If you enter only 12 digits, the 13th check digit is appended automatically.

Which file format (SVG or PNG) is best for printing?

SVG is a vector format that scales infinitely without pixelation, making it the industry standard for product packaging, commercial printing, and graphic design tools like Illustrator. High-DPI PNG is ideal for desktop label printers and Office documents.

Are my barcode numbers sent to a server?

No! All vector math and rendering runs 100% locally in your browser. Your SKU numbers and product codes remain completely private.
