# How to scan a QR code without an app

> You have not needed a QR scanner app since 2017. iPhones scan from the Camera app since iOS 11, and Android phones scan via the camera or Google Lens. On computers, a browser-based scanner decodes screenshots and webcam frames with nothing installed. Dedicated scanner apps are now mostly adware.

## Scanning went native in 2017

The QR scanner app died as a necessity years ago; the market just has not finished
noticing. The timeline:

| Year | What changed |
|---|---|
| **2017** | iOS 11 put QR scanning into the iPhone Camera app |
| **2017–2018** | Google Lens rolled out across Android cameras and the Google app |
| **2022** | Android 13 added a dedicated QR scanner tile to quick settings |

Effectively every smartphone sold since about **2018** scans QR codes with software it
shipped with. The per-device details are in the
[native scanning compatibility table](/docs/scanning/which-phones-can-scan-qr-codes-natively).

## On a phone

- **iPhone**: open **Camera**, frame the code, tap the banner. That is the whole
  procedure — the [iPhone page](/docs/scanning/how-to-scan-a-qr-code-on-iphone) covers
  the screenshot and Control Centre variants.
- **Android**: open the camera; if no link chip appears, use **Google Lens** or the
  Android 13+ quick-settings tile. Details on the
  [Android page](/docs/scanning/how-to-scan-a-qr-code-on-android).

Both platforms also decode codes from saved images — Live Text on iOS, Lens on
Android — so even the "code on my own screen" case needs no app.

## On a computer

Desktops never got a native scanner worth using, but the browser fills the gap: a
[client-side web scanner](/scan) decodes an uploaded screenshot, a pasted image or a live
webcam feed with nothing installed. The decoding runs in the browser itself, so the
image is never sent to a server — and you see the decoded text before anything opens,
which is safer than a camera app that launches links immediately.

## What scanner apps actually still offer

Honesty requires the short list. A dedicated app earns its install only for:

- **Batch work** — scanning hundreds of codes into a list, as in
  [inventory-style batch scanning](/docs/scanning/batch-scanning-many-qr-codes).
- **Hardware workflows** — warehouses and tills, where
  [dedicated 2D imagers](/docs/scanning/hardware-barcode-scanners-and-qr) beat any phone.
- **Feature phones** — KaiOS devices scan via apps, not the bare camera; see
  [scanning on feature phones](/docs/scanning/qr-scanning-on-feature-phones).

For everyone else, the app-store scanners are worse than the built-in route on every
axis: they add an install step, most are saturated with ads, and some log every decoded
URL to third parties. A camera that ships with your phone has no incentive to do either.
The fuller argument is on [do you need a QR scanner app](/docs/scanning/do-you-need-a-qr-scanner-app).

## The one habit that matters more than the tool

Whatever scans the code, **read the destination before opening it**. Native cameras show
the domain in the banner; a good web scanner shows the full decoded text. That pause is
the entire defence against [malicious codes](/docs/security/are-qr-codes-safe), and no
scanner app automates judgement.

## FAQ

### Do I need to download an app to scan a QR code?
No. Every iPhone since iOS 11 (2017) scans from the Camera app, and Android phones scan
via the camera or Google Lens. On a computer, a browser-based scanner needs no
installation.

### How do I scan a QR code without an app on iPhone?
Open the Camera app, point it at the code, and tap the banner that appears. For a code
already on the phone, long-press it in Photos or use the Live Text icon.

### How do I scan a QR code without an app on Android?
Open the camera and look for a link chip; if none appears, use Google Lens from the
camera, the Google search bar, or the Android 13 quick-settings QR tile.

### Are QR scanner apps safe?
Many are ad-supported and some log the URLs they decode. Since the built-in camera and
free browser-based scanners cover every normal case, the safest option is simply not to
install one.
