Frequently Asked Questions

Which barcode formats are supported? ↓

The generator supports Code 128 (standard for shipping and logistics), EAN-13 (international retail), UPC-A (North American retail), and Code 39 (industrial and inventory tracking).

Can I print labels directly from the browser? ↓

Yes. Use the "Print Barcode" action to format a high-contrast print preview optimized for standard thermal label printers and office laser printers.

Are any barcode numbers or product IDs uploaded to a server? ↓

No. The barcode encoding algorithm and rendering runs 100% client-side inside your browser. No data ever leaves your device.

What format should I download for crisp printing? ↓

SVG (Scalable Vector Graphics) is recommended for commercial printing because vector barcodes never pixelate or lose sharpness at any scale multiplier.
