Free tool
QR code generator
Paste a link, get a QR code. Free, no account, and the SVG prints at any size without going fuzzy.
What to do with it
Put it on a flyer, a business card, a market stall or the last slide of a talk. It points at whatever URL you gave it, so a link-in-bio page behind it means you can change where it leads without reprinting anything.
