Frequently Asked Questions

Why should I use a QR code API?
Integrate QR code generation into your app, website, or workflow with a simple HTTP request. The API supports all QR types (URL, WiFi, vCard, email, SMS, phone, location, event) and full design customization (colors, dot shapes, logo upload). It is the fastest way to go from idea to scannable QR code.
Is it safe to use QR codes?
Absolutely. A QR code is simply a visual encoding of data — it cannot install software or access personal information. The phone shows the content before acting on it, so users always verify the destination first.
Can I use the QR codes for commercial purposes?
Yes. QR codes created with Nofolo are yours to use however you want — business cards, product packaging, marketing materials, menus, signage, and more. No attribution required.
What size should I print my QR code?
For close-range scanning (business cards, table cards), print at least 1 inch (2.5 cm) across. For signage scanned from a distance, use 3-6 inches. Download as SVG for perfect quality at any size.
Does Nofolo support dynamic QR codes?
Yes. Create a free Nofolo dashboard account to generate dynamic QR codes. Dynamic codes use a redirect URL you can change anytime without reprinting, and include real-time scan analytics.
