About Us
QRCodeAB is a free, high-performance QR code generator and scanner created to make sharing links, Wi-Fi credentials, and contact details effortless. Designed with a strict privacy-first philosophy, QRCodeAB renders every code instantly in your browser without ever transmitting your content over the internet.
Our Mission
Our mission is to provide a reliable, privacy-respecting tool for everyone. In a world where data privacy is increasingly compromised, we believe that simple utilities like QR code generators should not be a vector for data harvesting. We are committed to keeping QRCodeAB free, fast, and secure.
Fast, Reliable, and Free
Unlike many other QR generation services, QRCodeAB will never surprise you with hidden fees, sudden subscription walls, or expiring QR codes. The codes you generate are static and contain your actual data, ensuring they continue to work indefinitely without requiring an ongoing service or account.
Why Choose QRCodeAB?
QRCodeAB provides a clean, ultra-fast, zero-bloat studio inspired by qrcode-monkey: eight content types (link, text, Wi-Fi, vCard, email, phone, SMS, location), styled dots and corners, brand colors, quiet-zone control, error correction levels, logo overlay, and one-click PNG/SVG/JPG downloads plus a built-in camera and image-upload scanner.
Designed for Professionals
Whether you're printing codes for a small flyer or a large billboard, QRCodeAB has you covered. By offering true vector SVG exports alongside high-resolution PNG and JPG formats, you get crisp, print-ready results that will never pixelate when scaled. Adjust error correction levels up to 'High' to guarantee readability even when a large logo is placed in the center.
How It Works
QRCodeAB leverages the power of modern web technologies to bring QR code generation directly to your browser. By utilizing the qr-code-styling library, we ensure that every QR code is generated efficiently and securely on your device. This means no server-side processing, no delays, and absolute privacy for your data.
Open Web Commitment
We built QRCodeAB to be a powerful progressive web application (PWA). You don't need to download a heavy native app from an app store just to scan or generate a code. Everything runs smoothly and natively inside your preferred web browser across mobile, tablet, and desktop devices.
Advanced Customization
Beyond basic generation, QRCodeAB offers advanced customization options. You can match the QR code to your brand by adjusting the dot styles, selecting custom colors for the foreground and background, and even embedding your company logo right in the center. The built-in error correction automatically adjusts to ensure your QR code remains scannable even with a logo.
Our Core Privacy Principles
QR codes often encode sensitive data: home Wi-Fi passwords, private contact cards, internal links. QRCodeAB was engineered so that data never has to leave your device.
- 100% Client-Side Rendering: Codes are drawn on your device with JavaScript. No content is sent to, processed by, or stored on our servers.
- On-Device Scanning: Camera frames and uploaded images are decoded locally with jsQR. Nothing is uploaded for analysis.
- Zero Tracking of Content: Telemetry records only anonymous counts (content type, size, format, scan mode). It never records payloads, images, or raw IPs.
- Offline-Friendly Output: Downloaded codes embed your data directly, so they scan without accounts, subscriptions, or expiry dates.
What You Can Create
Restaurant menus, event tickets, product packaging, business cards, classroom handouts, real-estate signs, app download links, payment pages, and guest Wi-Fi cards. Anywhere typing a URL is friction, a QR code removes it.
