Professional QR Code Generator

QR codes have become essential for modern marketing. Our Custom QR Code Generator allows you to embed your brand's personality into every scan.

Why Use Branded QR Codes?

  • Custom Logo Integration: Upload your logo to sit in the center.
  • Error Correction (Level H): Remain scannable even if partially damaged.

Secure and Data-Free

NJTools values your anonymity. Your custom logos are processed locally in your browser. Your data remains yours—no redirection, no tracking.

Advanced QR Engineering

Reed-Solomon Error Correction

NJTools utilizes Level H (High) error correction algorithms. This mathematical redundancy allows your QR code to remain functional even if up to 30% of the surface is covered by your custom logo or suffers physical damage.

Pixel-Perfect Rasterization

Our export engine transforms vector SVG data into a 500x500 high-density PNG using the HTML5 Canvas API. This ensures that every data module is sharp and clearly defined, preventing scanning failures on low-end mobile devices.

Developer's Privacy Note

"Unlike commercial QR generators that use tracking redirects (dynamic QRs), NJTools generates Static QR Codes. Your URL is encoded directly into the pattern. This means your links never expire, and your users' privacy is protected from third-party analytics trackers."
