Building BT QR Generator: Solving Paywalls, Watermarks & Privacy in QR Codes
Why we built a fast, free, privacy-first QR Code Generator with custom branding, zero watermarks, and zero subscription traps.
1. The Problem: The Broken State of Online QR Code Generators
QR codes have become an essential part of daily life. Whether you're running a small business sharing a digital menu, printing event banners, directing customers to a payment portal, or sharing Wi-Fi credentials with guests—QR codes are everywhere.
However, when you search online for a simple "QR Code Generator," the experience is often surprisingly frustrating and predatory:
- Subscription Paywalls & Expiration Traps: Many tools let you generate a code for free, but silently redirect your code through their proprietary servers. After 7 to 14 days (or after reaching 10-50 scans), your printed QR code suddenly stops working unless you pay $15–$45 per month!
- Ugly Watermarks: Free exports often plaster third-party logos or watermarks over your design, ruining your brand's aesthetics.
- Data Privacy Intrusion: Most web generators track every single scan, storing visitor IP addresses, location data, and device types on external servers without clear consent.
- Low Quality Exports: Cheap generators limit free downloads to tiny, pixelated PNG files that look blurry when printed on physical materials.
