Frequently asked questions

We build the image in your browser. There’s no scan analytics, hosted short links, or dashboard here—that’s what many dynamic QR services offer instead.

Treat Wi‑Fi passwords and private URLs like anything else on a shared machine: don’t leave them on screen for others to see.

Static: the full payload (link, text, vCard data, Wi‑Fi string) lives in the barcode. It keeps working offline once printed.

Dynamic: the code usually points to a short URL on someone else’s server; they can change where it goes and often show stats. That needs their product, not this page.

QR Tool only makes static codes. See static vs. dynamic for more.

A static QR code only holds one URL. Device-based routing needs an intermediate link (your own redirect page or a smart-link service) that reads the visitor’s device and forwards them.

This tool doesn’t host that redirect—use Link with a single store URL, or a URL from your site or provider that handles both platforms.

Not with a static code—the graphic is fixed. Make a new code and swap the file or print.

Editable destinations and reports come from dynamic QR providers; we don’t offer that here.

Contrast: dark on light (or the opposite) with a clear edge. Pale grays and glare confuse cameras.

Size: print big enough for how far away people stand.

Logo: if the center image is too large, shrink it or shorten what you encode.

Yes. We draw the logo on top and use strong error correction.

With a logo, stick to PNG. SVG is for vector output without that bitmap on top.

Recent iPhone and Android cameras usually offer to save a contact. Wording varies by OS.

If you only see raw text, any QR app that supports vCard can still save it.

It’s the same as giving someone the SSID and password—anyone who scans can join.

Use a guest network when you can, change the password if it leaks, and put the code where only guests should see it.
