Privacy-First QR Code Studio
Generate permanent, scannable ISO/IEC 18004 QR codes for website URLs, Wi-Fi network auto-login, vCard business contacts, and plain text. Computed 100% locally in your browser with PNG and vector SVG export.
Tip: Encode your direct URL so your printed QR code never expires or routes through third-party tracking servers.
Why You Should Always Generate QR Codes Client-Side
If you search for a "free QR code generator," many top results use a dark pattern known as a dynamic
redirect trap. Instead of encoding your actual website address (e.g.,
https://yourcafe.com/menu) into the black-and-white squares, they encode their own tracking URL
(e.g., https://qr-track.example/x98a2) and give you a 14-day free trial. After you print 5,000
business cards or table tents, they deactivate the redirect unless you pay a monthly subscription—and every
customer scan logs their IP address and device fingerprint on a third-party server.
GPDesk's Privacy QR Code Studio encodes your exact UTF-8 string directly into the ISO/IEC 18004 barcode matrix inside your browser:
- Permanent & Subscription-Free: Because the data is mathematically baked into the module grid, your QR code will work forever as long as your destination link exists.
- Safe for Wi-Fi Passwords: Generating a guest Wi-Fi QR code (`WIFI:T:WPA;S:MyNetwork;P:SecretPass;;`) on a server-side website transmits your home or office Wi-Fi password in plaintext to a remote database. Here, it never leaves your browser tab.
- Vector SVG Support for Commercial Print: Graphic designers working in Adobe Illustrator, Affinity Designer, or Canva can download crisp `.svg` paths that scale to billboard dimensions with zero pixelation.
QR Printing Checklist
- ✓ High Contrast Only: Always keep dark modules on a light background; never invert colors.
- ✓ Preserve Quiet Zone: Keep the 4-module white border intact so cameras detect corners.
- ✓ Minimum Print Size: Print at least 2 cm × 2 cm (0.8 in) on business cards.

Do QR codes generated on GPDesk ever expire?
Never. GPDesk generates static, direct-encoded QR codes. There is no intermediary redirect server, no scan limit, and no expiration date.
How does the Wi-Fi Auto-Connect QR code work?
Both iOS (iPhone Camera app) and Android natively recognize the

Why does my QR code get denser when I type a long URL?
QR codes scale from Version 1 (21×21 modules) up to Version 40 (177×177 modules) as byte length increases. Shorter URLs require fewer modules, resulting in larger, easier-to-scan squares for print media.
Should I download PNG or SVG for my designer?
Use PNG for web pages, email signatures, and Word documents. Use SVG for professional print layouts (menus, packaging, banners) so the edges remain razor-sharp at any DPI.
