Branded QR code generator

Python script that produces logo-centred, gradient QR codes and checks that each one still scans

Branded QR code for Omo Beeza Ministry materials1 / 4

Churches and ministries wanted QR codes for maps and forms that carry their logo. The script generates a crisp SVG and a styled PNG, then decodes the result to prove it still works.

The problem

Putting a logo in the middle of a QR code can make it unreadable, and nobody finds out until someone tries to scan a printed flyer.

What I built

Codes use the highest error-correction level so the logo can cover part of the pattern. Modules are drawn rounded with a radial gradient, and every output is decoded with zxing-cpp before it is saved.

Results

  • QR codes delivered for a church map, Gospel Work forms and Omo Beeza materials.

Features

  • SVG and styled PNG output
  • Centred logo with high error correction
  • Rounded modules and gradient fill
  • Automatic scan verification
  • Simple HTML page for quick use
