Free QR Code Generator: How QR GEN by Dazzle Tech Creates 45+ Types of QR Codes Instantly

In today’s digital-first world, QR codes have become one of the most powerful tools for connecting physical and digital experiences. From restaurant menus and business cards to marketing campaigns and event check-ins, QR codes are everywhere. But most QR code generators online are cluttered with ads, require paid subscriptions for advanced features, or upload your data to their servers. That is why Dazzle Tech built QR GEN — a completely free, privacy-first QR code generator with over 45 QR code types and 24 frame designs.

What is QR GEN?

QR GEN is a free online QR code generator built by Dazzle Tech LLC. It supports over 45 different QR code types, offers bulk generation, includes 24 professionally designed frame styles, and lets you add your logo to the center of any QR code. Best of all, everything is 100% client-side — your data never leaves your device, and no account is required.

45+ QR Code Types — Everything You Need

What makes QR GEN stand out is the sheer variety of QR code types it supports. Most free generators only handle basic URL QR codes. QR GEN goes far beyond that:

• URL / Link — Convert any website link into a scannable QR code for marketing materials, business cards, and packaging.
• WhatsApp — Let customers message you instantly with a pre-filled phone number and message.
• WiFi — Share WiFi credentials without typing passwords. Supports WPA, WPA2, and WEP encryption.
• vCard Contact Card — Share your full contact details (name, phone, email, company) in one scan.
• Email — Pre-compose emails with recipient, subject, and body text ready to send.
• Location / Map — Encode GPS coordinates with a live map preview that opens in Maps apps.
• Google Review — Link directly to your Google Business review page to boost your ratings.
• Payment — Generate QR codes for PayPal, Venmo, UPI, and cryptocurrency wallet payments.
• PDF, PPTX, Excel, Google Docs — Share documents and files with a single scan.
• Social Media — Create QR codes for TikTok, Instagram, X (Twitter), LinkedIn, Snapchat, Reddit, and Spotify.
• Bulk Generator — Paste multiple URLs and generate all QR codes at once, downloadable as a ZIP file.

24 Frame Designs — Make Your QR Codes Stand Out

Generic black-and-white QR codes work, but they do not stand out. QR GEN offers 24 professionally designed frame styles across 6 categories — Basic, Premium, Business, Holiday, Social, and Creative — with call-to-action labels like “Scan Me”, “View Menu”, “Leave Review”, and more. These frames make your QR codes look polished and professional, whether you are placing them on a restaurant table, product packaging, or an event flyer.

Logo Overlay — Brand Your QR Codes

QR GEN lets you upload your company logo and place it in the center of your QR code. It uses the highest error correction level (H), which means your QR code will still scan perfectly even with a logo overlay taking up space in the center. This is a premium feature on most platforms — on QR GEN, it is completely free.

Custom Colors and Styles

Brand consistency matters. QR GEN lets you customize the foreground and background colors of your QR code to match your brand identity. You can also choose from three dot styles — Square, Rounded, or Dots — to give your QR codes a unique visual personality. The tool automatically validates color contrast to ensure your QR code remains scannable.

5 Export Formats for Every Use Case

Once you have created your QR code, you can download it in five formats: PNG (high-resolution for digital use), SVG (vector for print scaling), JPEG (compressed for web), WebP (modern web format), and PDF (print-ready document). Whether you are printing on a banner or embedding in a website, QR GEN has the right format for you.

100% Privacy — Your Data Never Leaves Your Device

This is one of QR GEN’s most important features. All QR code generation happens entirely in your browser using client-side JavaScript. No data is sent to any server. This means whether you are creating a QR code with your WiFi password, your home address, or your business payment details, that information stays completely private on your device.

Who Should Use QR GEN?

QR GEN is useful for a wide range of people and businesses. Restaurant owners can create WiFi and menu QR codes. Marketing managers can generate branded URL QR codes for campaigns. Event planners can create calendar and check-in QR codes. Real estate agents can use the bulk generator to create QR codes for all their listings at once. Small businesses can use Google Review QR codes to boost their ratings. Designers can create logo-branded QR codes for their clients.
