# Barcode Generator

Generate Code 128, EAN-13, UPC-A, and more barcodes online. Customize bar width, height, and font. Download as SVG or PNG.

## How It Works

1. **Enter data and pick a format** — Type the value and select the barcode format (Code 128, EAN-13, UPC-A, etc.).
2. **Customize appearance** — Adjust bar width, height, font size, and toggle text display.
3. **Download** — Download as PNG for print or SVG for scalable graphics.

## FAQ

### Which format should I use?

Code 128 for general text/numbers, EAN-13 for retail products, UPC-A for North American retail, Code 39 for industrial use.

### Why does my barcode show an error?

Each format has specific requirements. EAN-13 needs 12-13 digits, UPC-A needs 11-12 digits. Check the format requirements.

### Are the barcodes scannable?

Yes. All generated barcodes follow the official specifications and are scannable by standard barcode readers. For URLs or WiFi credentials, a [QR code](https://varstatt.com/toolkit/qr) is usually more practical.
