How to Create a Custom QR Code with Logo, Colors, and Frames

Step-by-step tutorial for generating a branded QR code with a custom logo, colors, and dot styles, plus best practices to keep it scannable.

A QR code does not have to be a plain black-and-white square. With the right customization, a logo, brand colors, and styled dots, you can make it recognizable while keeping it fully scannable. This tutorial covers the full process and the trade-offs that affect scannability.

What a QR code stores

A QR (Quick Response) code encodes data such as a URL, plain text, WiFi credentials, or a vCard contact into a 2D matrix of modules. Phones decode it by scanning the three large finder patterns in the corners plus the data modules in between. Customization must not interfere with these patterns.

Step-by-step

  1. Choose your data type: URL, text, WiFi, or vCard.
  2. Enter the content. For URLs, use the full https:// link.
  3. Pick a dot style and an eye (corner) style that matches your brand.
  4. Set foreground and background colors. Keep high contrast.
  5. Optionally upload a logo in the center, keep it small (under ~22% of the code area).
  6. Generate and download as PNG, SVG, or PDF.

Best practices for scannable QR codes

  • Maintain high contrast: dark modules on a light background scan most reliably.
  • Do not invert colors (light modules on a dark background); many readers struggle.
  • Keep the logo small and centered so it does not cover the finder patterns or too much data.
  • Add a "quiet zone", a margin of background color around the code, of at least 4 modules.
  • Test on multiple phones and lighting conditions before printing.

SVG vs PNG vs PDF

PNG is fine for screens and small prints. For large-format printing such as posters or packaging, use SVG or PDF so the code stays crisp at any size, pixelation can break scannability when scaled up.

Tip: the more data you encode, the denser the code and the harder it is to scan at small sizes. Use a short URL when possible.

Privacy

A client-side QR generator renders the image entirely in your browser. Your URL, WiFi password, or contact data never leaves your device, which matters especially for WiFi and vCard codes that contain sensitive credentials.
