About QR Code Studio
Engineered to bring transparency, design freedom, and uncompromised privacy back to QR code generation.
Our Core Philosophy
Too many online QR code tools lock users into deceptive subscription traps: they generate temporary dynamic redirect URLs that expire after 14 days, breaking physical signage, menus, and business cards unless users pay exorbitant monthly fees.
QR Code Studio was built on a different promise: standard, static QR codes that encode your data directly, remain completely functional forever, and generate locally in your browser without tracking, cookies, or remote logging.
Technical Architecture
- Backend: Clean, modular PHP 8.1+ supporting Apache, XAMPP, and standard shared hosting environments.
- Frontend: Vanilla ES6+ JavaScript, Bootstrap 5.3, and SVG/Canvas HTML5 rendering pipelines.
- QR Generation Engine: Standards-based
qr-code-stylingwith custom module matrix calculation. - Document Generation: Pure client-side PDF synthesis with
jsPDFand ZIP archive creation withJSZip. - Accessibility: WCAG 2.1 contrast compliance checks, screen-reader friendly attributes, and responsive breakpoints.
