Frequently Asked Questions
- Is this barcode generator free?
- Yes, completely free with no limits, no watermarks, and no account needed.
- Are my barcodes generated on your server?
- No. All barcodes are generated entirely in your browser using JavaScript. Nothing is sent to any server, so your data stays 100% private.
- What is the difference between PNG and SVG?
- PNG is a pixel-based image — ideal for digital use, printing at a fixed size, or embedding in documents. SVG is vector-based, meaning it scales to any size without losing quality — perfect for print, labels, and packaging.
- What should I use for retail product barcodes?
- For retail products sold internationally, use EAN-13. For US retail products, use UPC-A. Both require officially registered GS1 numbers for commercial use.
- Can I use a QR code for a website link?
- Yes — just paste your full URL (including https://) into the QR Code content field and generate. Anyone who scans it will be taken directly to your page.
