Free QR Code Scanner (No App Needed)

Your phone's camera has scanned QR codes for free since 2017 — so it's wild that some "QR scanner" apps in the app stores charge a weekly subscription (often around $3.99/week, which is roughly $156 a year) for the same thing, hiding the free option in tiny grey text and burying the complaints under fake reviews. QR Puppy is a free scanner that opens right in your browser: no download, no account, no subscription, no ads. Point your camera or drop in an image, and for links it shows you exactly where the code goes before you tap — decoded entirely on your device.

How to make it

1. Open the scanner (no install — it just runs in your browser).
2. Tap Use camera and point it at the code, or Upload image to scan a screenshot or photo.
3. For a link, read the safety inspector — it flags shorteners, tracking parameters and look-alike domains before you open anything.
4. Copy the result, open the link, or scan another. Nothing is uploaded, ever.

Frequently asked questions

Do I really not need to install an app?

Correct. QR Puppy's scanner runs in your web browser on iPhone and Android. There's nothing in an app store to download and nothing to subscribe to.

Why do some app-store QR scanners charge a weekly fee?

Because people don't realize their phone already scans QR codes for free. Those apps rely on a hidden "free trial → auto-renew" flow and inflated reviews. You never need to pay to scan a QR code.

Is scanning private?

Yes. The camera frames are processed on your device and never sent anywhere — there's no server involved. QR Puppy has no tracking and no accounts.

Can it warn me about dangerous QR codes?

Yes. For links, the built-in inspector checks for URL shorteners, tracking parameters, punycode look-alike domains, raw IP addresses and embedded credentials, and shows the real destination before you tap.
