Free Online QR Code Generator with Logo Integration
Overview
A clean, professional, and high-performance utility for generating custom QR codes. Users can input URLs, text, or contact information, apply custom colors, and overlay a brand logo image. The application provides a real-time preview and allows downloading the result as a PNG or SVG.
Core Features
- Real-Time Generation: Update the QR code instantly as the user types or adjusts settings.
- Logo Embedding: Simple file upload system to center a custom image on the QR code.
- Styling Controls: Custom color selectors for both the dark and light modules of the code.
- Error Correction Levels: Options to adjust the QR code's density and scan reliability (Low to High).
- Download Formats: Export options for high-resolution PNG or SVG files.
- Mobile Optimization: Fully responsive interface that works on desktop, tablet, and mobile devices.
UI/UX Design
- Layout: A modern, two-column "SaaS" style dashboard.
- Left Panel (Configuration): A scrollable form containing text input, file upload for the logo, color pickers, and settings sliders.
- Right Panel (Preview): A sticky display area showing the live QR code preview and a prominent "Download" button.
- Aesthetics: Clean, light-mode design using a high-contrast palette. Use whitespace, soft shadows (elevation), and rounded corners to provide a polished, premium feel.
- Micro-Interactions: Smooth CSS transitions when switching settings or uploading files. Use loaders/spinners for image processing to provide immediate visual feedback.
Color Palette
- Primary: Indigo/Blue (#4F46E5) for action buttons.
- Background: White (#FFFFFF) and Soft Gray (#F9FAFB) for sections.
- Text: Slate (#1E293B) for readability.
- Border: Slate-200 (#E2E8F0) for subtle separation.
Technical Constraints & Implementation
- Single-File Architecture: All CSS, HTML, and Vanilla JavaScript must reside within one single
.htmlfile. No external dependencies requiring build steps. - CDN Usage: You may include the
qrcode.jsorqrcode-generatorlibrary via a trusted CDN for generation logic. - No Persistence: Do NOT use
localStorage,sessionStorage, or cookies. The app must rely on in-memory variable state. All inputs are cleared on refresh. - Iframe Compatibility: The app is designed for a sandboxed iframe. Do not attempt to trigger pop-ups or use
window.alert. Use custom modal components built with HTML/CSS if user alerts are necessary. - Browser-Based: All processing (image compositing, QR rendering) must occur client-side on the user's local machine for maximum privacy and performance.
- Responsive: Utilize CSS Flexbox/Grid to collapse the two-column layout into a single vertical column on mobile devices.
