Turn a URL into a QR code that is also a picture: this tool blends a scannable code into an image generated by Stable Diffusion with ControlNet, so the pattern follows your prompt while staying readable by phones. Free, no account. Best results with high-contrast prompts and short URLs.

How to use AI QR code generator

  1. Enter the URL or text to encode; shorter content gives a simpler, more readable code.
  2. Write a prompt for the image, for example "a japanese garden, ink painting, high contrast".
  3. Keep the ControlNet strength around 1.2 to 1.5 for readability, lower for a more artistic result.
  4. Generate, then test the code with your phone camera before using it.

Limits and questions

Why does my code not scan?

Too artistic: raise the ControlNet strength, use a shorter URL, add a plain border and more contrast in the prompt. Always test on two phones.

Can I use my own logo or colours?

Colours yes, through the prompt. Exact logos no: the image is generated, not composited. Generate several and pick the best.

Why is the tool slow or unavailable?

This demo is hosted by a third party (Hugging Face Space) and embedded here; it can be slow, queued or temporarily unavailable when the host is busy. Nothing to install, no account needed.
