Anyone know of a good QR code generation service for high-res images? (lemmy.ml)

Basically, I want to make an artistic QR code of a website I made for my girlfriend, and then ship her a jigsaw puzzle of the QR code art.

There's lots of services online that generate AI image QR codes, but the problem is they all max out at like 1024x1024. I need something at least 5x bigger than that for a physical, 1000 piece jigsaw puzzle. If I use an upscaler, it looks uncanny when you zoom in.

Basically, I want to make something like this, but much higher res: https://i.imgur.com/TeDvEgL.png

Any ideas?

You can also generate a lower quality image and use an AI upscaler to increase the size of your artistic QR code.

I just Googled "SVG qr code generator" and found this: https://qrplanet.com/qr-code-generator-svg

SVG is a vector format so you can expand or shrink it without losing quality. So you could maybe bring it to 5000x5000 with illustrator/krita and then export to a raster format (jpg/png) so you can modify it how you want

That's great but what I'm trying to do is artistic QR generation like the example I linked in the post

Hmm I found this, looks like I could clone it and adjust the output resolution if I get A1111 working locally: https://huggingface.co/spaces/huggingface-projects/QR-code-AI-art-generator

You can try HordeNG which has the ability to generate QR codes within a picture of your choosing. You can choose a resolution of 1024x1024 and a 4x upscaler which would bring the resolution to 4096x4096.

I don't think all of that is possible with an account with no kudos (credits), but feel free to PM me, I can gift you an api key with some kudos to play around.

This was what I came to suggest for you

I actually forked this and customized the code. I'll publish it soon so others can follow
