FREE Customizable Branded QR Code Generator
Branded QR Code Generator
Tip: For best scan results, keep strong contrast and avoid oversized logos.
The Branded QR Code Generator is a professional, web-based WordPress tool developed by O2 Digital Agency to help users design fully personalized and visually consistent QR codes that align perfectly with their brand identity.
It offers live, on-page QR code generation, full customization control, and the ability to embed your own logo directly inside the QR — all within a clean, responsive, and intuitive interface – for FREE.
⚙️ QR Code Generator Main Features
1. Instant QR Code Creation
The tool generates a high-quality, fully scannable QR code in real time.
You simply enter a URL or any text, and the generator instantly produces a ready-to-use QR image in the preview panel.
2. Brand Logo Integration
Users can upload their own brand logo (in PNG, JPG, or SVG format) and have it seamlessly embedded in the center of the QR code.
The logo keeps its original aspect ratio — no distortion, no forced cropping — and is displayed on a clean white “plate” with a 10-pixel padding for optimal readability and scanning performance.
3. Customizable Colors
You can select the foreground and background colors of the QR code, allowing perfect adaptation to your brand palette.
This makes it ideal for marketing materials, packaging, or any visual campaign that requires aesthetic cohesion.
4. Live Preview Panel
The right side of the interface is a dynamic Preview Area.
Before generating, it shows a technical grey placeholder — a subtle designer-style preloader image.
After generating, this area instantly displays the real PNG version of your QR code exactly as it will look upon download or print.
5. Export & Clipboard Options
- Download PNG: Exports the QR code as a high-resolution PNG image, ideal for digital or print use.
- Copy to Clipboard: Instantly copies the PNG image into your clipboard for quick use in design software, chat apps, or CMS editors.
Both options use modern browser APIs for maximum compatibility and efficiency.
6. Logo Scaling Control
A slider lets you control the logo’s relative size (10–40% of QR width).
This ensures perfect balance between brand visibility and QR code scannability.
7. Advanced Error Correction
Four selectable Error Correction Levels (L, M, Q, H) ensure that your QR remains readable even with logos or minor visual obstructions.
Default level “H” offers the highest resilience — recommended when embedding logos.
8. Responsive & Accessible Design
The interface is built with smooth CSS and clean HTML, optimized for all screen sizes.
It’s also accessible: keyboard navigation, descriptive ARIA labels, and readable contrast levels.
9. Performance-Optimized
The tool uses client-side JavaScript (no server calls, no data storage) — everything happens locally in the browser, so it’s fast, private, and secure.
10. GDPR & Security Safe
No uploaded logo or QR code data is ever sent or stored on external servers.
All processing happens in real time inside your browser using canvas rendering — fully GDPR-compliant by design.
🧠 How It Works — Step-by-Step
- User Inputs Data:
The user enters a URL or text, selects QR code colors, error correction level, and desired preview size. - Logo Upload:
When clicking “Attach Logo”, the browser’s file picker opens.
Once selected, the file is read via a JavaScript FileReader API, converted to a base64 data URL, and stored temporarily in memory (never uploaded). - QR Code Rendering:
When clicking “Generate”, the tool uses the QRCode.js library to draw a high-density QR matrix on an invisible canvas.
A second rendering phase draws a flat white center plate with rounded corners, then the uploaded logo is drawn inside — respecting its aspect ratio and padding. - PNG Creation:
The canvas image is converted into a Blob (binary object) representing a downloadable PNG file.
This Blob is displayed in the Preview Area as a live image and stored in memory for Download / Copy actions. - Preview Display:
The preview section replaces the placeholder with the actual PNG QR code, giving an exact visual representation of the final file. - Download / Copy:
- When the user clicks Download PNG, the tool regenerates the QR at the defined export size (e.g., 1024px or higher) and automatically triggers a browser download.
- When clicking Copy to Clipboard, it fetches the same image Blob and copies it directly to the system clipboard using the Clipboard API (supported on HTTPS).
- Clear Function:
The Clear button resets everything: revokes old URLs, clears the preview image, empties logo data, and restores the default grey placeholder. - Memory Management:
Object URLs are properly revoked after each generation or on page unload, ensuring no memory leaks.
