How It Works
The generator uses the JsBarcode library to render barcodes directly onto an HTML canvas in your browser. No data is sent to a server — everything happens locally. The canvas is then exported as a PNG for download.
Example
To create a CODE128 barcode for a shipping label with tracking number 1Z999AA10123456784: select CODE128, enter the tracking number, click Generate. Download the PNG and include it in your label document.
