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.
Link types at a glance
| Link type | Example format | Routing |
|---|---|---|
| App Store (iOS only) | apps.apple.com/app/id123456789 | Opens App Store on iOS; may confuse Android |
| Google Play (Android only) | play.google.com/store/apps/details?id=com.example | Opens Play Store on Android |
| Smart / universal link | get.example.com/app | Device-detected; one code, both platforms |
For events and printed materials, a smart link is almost always the right choice — the same QR code works whether the person scanning has an iPhone or an Android phone.
Sizing guidelines for print
The minimum reliable print size for close-up scanning (business card, counter card) is about 2 × 2 cm. For posters or signage viewed from a distance, scale proportionally — a widely cited rule of thumb is at least 1 cm of code width for every 10 cm of intended scanning distance. At a trade stand where people scan from a metre away, print the code at 10 × 10 cm or larger.
For digital use (slides, web, email), SVG output stays sharp at any size. PNG is fine for screen but may look pixellated if stretched; download at the largest PNG size available if you might scale it up later.
Using a smart link you control
If you point the QR code at a smart link on a domain you own — rather than directly at an App Store URL — you gain an important advantage: you can change where the link redirects without reprinting the code. This lets you update a store listing URL if your app’s identifiers change, redirect to a web fallback if the app is temporarily unavailable, or swap the destination after a rebrand. Everything is generated in your browser, so nothing is uploaded.
