QR Diffusion

QR Diffusion is a web app that generates artistic QR codes by combining Stable Diffusion image generation with ControlNet, a technique that lets an image be shaped around an existing pattern. Instead of a plain black-and-white square, the resulting QR code is baked into an AI-generated image built from a text prompt, so the code can resemble a landscape, object, or pattern while still remaining scannable. The site offers three difficulty levels, from Beginner presets up to an Expert mode that exposes the underlying Stable Diffusion and ControlNet settings directly. QR Diffusion, made by Key Vision s.r.o., is aimed at marketers, small businesses, and creators who want QR codes that stand out in print or on screen and are more likely to get scanned than a standard code. Beyond static image generation, the platform supports dynamic QR codes that can be edited after creation, tracked through an analytics dashboard, and used with long URLs. It ships more than 50 pre-built templates covering seasonal and lifestyle themes, and it can also embed a QR code into an existing image supplied by the user. The free tier covers basic QR code art generation; a paid subscription unlocks more customization, faster generation, and priority support. The company notes that some artistic QR codes can be harder to scan on certain devices and says it is still working to improve compatibility.
