What happens when someone scans a social QR code?

With one profile filled in, the code opens that profile directly. With two or more, it opens a simple hosted link page listing all of them, and the scanner picks, like a mini link-in-bio for the physical world.

Do I paste my handle or the full URL?

Either works. Type @yourname or paste the full profile URL: we build the correct link for each platform (instagram.com/you, x.com/you, and so on) automatically.

Can I add or change profiles later?

The single-profile version is baked into the code, so it cannot change. The multi-link page is hosted, so the code stays scannable, but the set of links is fixed in the code too, so reprint if your profiles change.

Is this free? What is the catch?

Free forever, no signup, no watermark. The code is generated in your browser, and the link page carries no ads or tracking.

Which platforms are supported?

Instagram, X / Twitter, LinkedIn, YouTube, TikTok, GitHub, Facebook, plus a plain website link for anything else: a portfolio, a Linktree, a blog.

Before you print

How big should it be?

Rule of thumb: printed width ≥ scanning distance ÷ 10. Pick the surface above and the studio sizes the code for you, then checks the printed module size against what a press can actually hold.
