Frequently asked questions
- Is the barcode generator free?
- Yes — completely free with no sign-up, no watermark, and no limits.
- Is my data uploaded anywhere?
- No. Barcodes are generated locally in your browser; nothing you type is sent to a server.
- Which barcode type should I pick?
- CODE128 handles almost any text or number and is the safest default. Use EAN-13 or UPC-A for retail products, CODE39 for asset tags, and ITF-14 for shipping cartons.
- Why does it say my value is invalid?
- Some types require a specific format — for example EAN-13 needs 12–13 digits and UPC-A needs 11–12 digits. Switch to CODE128, or match the required length.
- Will the barcode actually scan?
- Yes. It's drawn on a white background with true black bars at a scannable resolution, and downloads as a clean PNG you can print or place anywhere.
- Can I use it on my phone?
- Yes — it works in any modern browser.
