About qrnch
qrnch is a free, browser-side QR code generator. Every QR code is created locally in your browser using JavaScript — your URLs, WiFi credentials, contact information, and email content never leave your device. No server, no account, no tracking.
QR codes are everywhere in 2026: restaurant menus, business cards, product packaging, conference badges, office WiFi signs, and print advertising. They bridge physical materials to digital destinations with a single camera scan. qrnch makes generating them fast, private, and completely free.
Four modes are supported. URL / Text encodes any URL or plain text — the most common use case. WiFi generates a code that, when scanned, prompts iOS or Android to join a network automatically — no typing required, ideal for offices, cafes, and events. Contact creates a vCard 3.0 QR code that saves a contact directly to the phone's address book when scanned. Email generates a pre-filled mailto link with optional subject and body.
Download your QR code as a PNG at 128, 256, or 512 pixels. For print materials, use 512px and ensure your print dimensions are at least 1×1 inch at 300 DPI. High error correction (level H) is used by default, so QR codes remain scannable even when partially obscured, printed at small sizes, or placed on textured backgrounds.
Frequently asked questions
Is this QR code generator free?
Yes — completely free, no sign-up, no account, no email. Generate and download as many QR codes as you need.
Does my data get uploaded to a server?
No. qrnch runs entirely in your browser. Your URLs, WiFi passwords, and contact details are never transmitted anywhere. You can use it offline once the page has loaded.
What QR code types are supported?
URL/Text (any URL or plain text), WiFi (WPA/WPA2/WPA3/WEP/open networks — scan to join automatically on iOS 11+ and Android 10+), Contact (vCard 3.0 format — scan to save directly to address book), and Email (pre-filled mailto with optional subject and body).
What formats can I download?
PNG at your chosen size (128, 256, or 512 pixels). PNG is the most widely supported format for print, web, presentations, and apps. Use 512px for the sharpest results in print.
How large should my QR code be for print?
At minimum, 1×1 inch (2.5×2.5 cm) at 300 DPI for reliable scanning from a normal distance. For business cards or small stickers, keep the QR content short — shorter URLs and simpler data produce fewer modules and scan more reliably at small sizes.
Will a WiFi QR code work on iPhone and Android?
Yes. The native Camera app on iOS 11+ and Android 10+ can scan WiFi QR codes and offer to join the network automatically. Select WPA/WPA2/WPA3 for most modern routers. For open (password-free) networks, select "None."
How do I add the QR code to a website or document?
Download the PNG, then insert it like any image. In HTML: <img src="qrnch.png" alt="QR code">. In Word or Google Docs: Insert → Image. In Canva or Figma: drag and drop the PNG directly onto your canvas.
Can I use these QR codes commercially?
Yes. QR codes generated by qrnch are yours to use for any purpose — personal, commercial, print, or digital — with no attribution required.
