FAQ
- Why does checksum validation fail?
- EAN and UPC formats require a valid final check digit. Enable auto checksum for short inputs or provide the full validated code.
- Which format should I use for retail labels?
- Common retail formats are EAN-13 internationally and UPC-A in North America. Use your retailer or POS requirements as the source of truth.
- Should I download SVG or PNG?
- Use SVG for print-ready output and scaling. Use PNG for quick digital sharing.
