Can one QR code work for both iOS and Android?

Yes — paste a smart or universal link that detects the visitor's device and forwards them to the correct store. A direct App Store or Play Store link only targets one platform.

Does it add the https prefix for me?

If your link has no scheme it is treated as an https URL; links that already start with a scheme are encoded exactly as entered.

Does the QR code expire?

No. The QR code simply encodes your URL, so it works for as long as that link does. If you point it at a smart link you control, you can change where it redirects without reprinting the code.

What size should I print an app QR code?

A minimum of about 2 x 2 cm (0.8 inches) is reliable for close-up scanning. For posters scanned from a distance, scale up proportionally — a good rule is at least 1 cm of width for every 10 cm of scanning distance.

Is my link uploaded anywhere?

No. The QR code is generated entirely in your browser; nothing is sent to a server.

App Link QR Code Generator

The App Link QR Code Generator turns a download link into a scannable QR code so people can install your app in one scan instead of searching a store. It is ideal for posters, flyers, business cards, packaging, slide decks and event stands — anywhere a printed code beats typing out a long store URL.

How it works

You paste a download URL — an Apple App Store link, a Google Play link, or a smart/universal link — and the tool encodes it directly into a QR code matrix that any phone camera can read. If your link has no https:// scheme, it is treated as an https URL; links that already include a scheme are encoded exactly as entered. For a single code that serves both platforms, use a smart link that detects the visitor’s device and forwards iOS users to the App Store and Android users to Google Play. The finished code can be downloaded as a crisp PNG or a scalable SVG.

Example

Link type	Example	Routing
App Store	apps.apple.com/app/id123456789	iOS only
Google Play	play.google.com/store/apps/details?id=com.example	Android only
Smart link	get.example.com/app	Both, auto-detected

Pasting a smart link produces one QR code that works for every device, then you download it for print or screen. Everything is generated in your browser, so nothing is uploaded.
