Understanding 1D Barcode Symbologies
Linear barcodes (1D barcodes) use a parallel sequence of alternating black bars and white spaces to encode textual or numeric data. This pattern is easily decoded by standard optical lasers and camera imaging systems to fetch product references instantly.

Frequently Asked Questions (FAQ)
Q: Why am I getting an error when typing alphanumeric characters?
A: Certain barcode types like EAN-13, EAN-8, and UPC-A strictly support numeric data only. Additionally, they require an exact length of characters to complete validation checks. If you need to encode arbitrary mixed text, switch your Barcode Type selection to Code 128 or Code 39.
Q: Which file format should I use for commercial printing?
A: We strongly recommend downloading the SVG format. Because SVG files are vector-based, they will not pixelate, blur, or lose contrast when printed on thermal label printers, ensuring the highest scanning rate.
Q: Can I use this tool completely offline?
A: Yes! Once the website finishes loading, all computation logic and canvas encoding are performed entirely on your local machine using client-side JavaScript. Your data never traverses the internet.
