AI-generated QR codes are the next big thing in marketing.

And it's completely free.

Here's my full tutorial on how to do it in 5 simple steps:

(Try scanning the image below) Image
Step 1: Get your QR code

Go to Google and search for a QR code generator.

There are a ton of free options. I used the first unsponsored link.

Enter the link that you want the QR code to redirect to.

Click download JPG, and wait 5-10 seconds.
Step 2: Access Stable Diffusion

If you don't have Stable Diffusion locally installed, here's the easiest alternative to access it on the cloud.

Go to rundiffusion.com

Sign up and get 7 minutes ($0.13) of free credits.

Step 3: Settings

Checkpoint: dreamshaper_6

Sampling: DPM++ 2M Karras

Scroll down, upload your QR code to ControlNet 0, and enable.

Preprocessor: select "inpaint_global_harmonious."

Model: select the model that has "brightness" at the end.

Decrease Control Weight to 0.35
Step 4: Settings Continued

Switch to ControlNet 1, upload your QR code, and enable.

Preprocessor: select "inpaint_global_harmonious."

Model: select the model that has "tile" at the end.

Decrease Control Weight to 0.65, Starting to 0.35, Ending to 0.75.
Step 5: Enter your prompt

I used:

Prompt: masterpiece, best quality, mecha, no humans, black armor, blue eyes, science fiction, fire, laser canon beam, war, conflict, destroyed city background

Negative prompt: UnrealisticDream, FastNegativeEmbedding

Generate your QR code.
That's it!

You can try different versions by just clicking generate again.
