Advanced Barcode Standards
100% Client-Side Generation
Inventory IDs, shipping tracking numbers, and product SKUs can be proprietary business data. By rendering barcodes on the HTML5 Canvas, your data is processed safely in your local RAM and never uploaded to an external API.
CODE128 (Universal)
The modern standard for non-retail logistics. CODE128 supports the entire ASCII character set (numbers, upper/lower case letters, and symbols) while maintaining high data density, making it perfect for custom internal SKUs.
EAN-13 & UPC (Retail)
These strictly numeric formats are mandated for global retail points-of-sale. EAN-13 (Europe/Global) requires exactly 12 or 13 digits, while UPC-A (US/Canada) strictly requires 11 or 12 digits. Invalid characters will cause an error.
ITF-14 (Logistics)
The Interleaved 2 of 5 standard used primarily for shipping boxes and wholesale multi-packs. It handles 14 numeric digits and is optimized for printing on low-quality corrugated cardboard without losing scan reliability.
High-Contrast Rendering
Laser scanners rely heavily on light absorption. While you can customize colors, it is crucial to maintain high contrast (e.g., black lines on a white background). Red lines or dark backgrounds often cause laser scanners to fail.
Lossless Canvas Exports
By bypassing traditional image tag generation, the script extracts the raw pixel data directly from the `
