Just a note, instead of encoding the picture in the full destination URL, you can encode the picture into the padding section between the URL and the Reed-Solomon section, thus permitting the use of any URL. I used this technique a long time ago on qrpixel.com but forgot to renew the domain, oops... http://web.archive.org/web/20160423015339/http://www.qrpixel.com/ http://web.archive.org/web/20160423015339/http://www.qrpixel... Also for information about how this works, Russ Cox did a good article on it, calculating using the R-S section as well: https://research.swtch.com/qart https://research.swtch.com/qart

Wow, I really like what qrpixel did! Do you know of any alternative tools (that are still around) that work the same way?

Can you deploy it somewhere? It seems very useful. Netlify should work great if it's a static page.
