## How it works

3. Set the bar width and height, then Process and download the PNG.

## Use cases

## Frequently asked questions

### Which barcode type should I pick?

EAN-13 for global retail products, UPC-A for US retail, EAN-8 for very small packaging, Code 128 for any general-purpose label with letters and numbers, and Code 39 for industrial asset tags. If unsure, Code 128 is the safest general-purpose pick.

### Do I have to calculate the check digit?

No. For EAN-13, EAN-8, and UPC-A you can type the number without the final check digit and it will be added automatically. If you do include it, it must be correct.

### What characters can I use in Code 128 and Code 39?

Code 128 accepts any printable ASCII character up to 80 characters. Code 39 is more restrictive: uppercase A-Z, digits 0-9, and the symbols -. $/+% with a space, up to 80 characters.

### What format and resolution do I get?

A high-resolution PNG with a white background, sized by the bar width and height you pick. Crisp enough for print or screen, scannable by any standard barcode reader.
