If you're wondering how to scan a QR code with iPhone, the short answer is you probably already can — every iPhone running iOS 11 or later scans QR codes natively through the Camera app, no download required.
Quick Answer
Open the Camera app, point it at the QR code, and tap the notification banner that appears at the top of the screen. If nothing happens, check Settings → Camera → make sure "Scan QR Codes" is turned on. For a QR code that's already a screenshot or saved photo rather than in front of you, open it in Photos and tap the Live Text icon, or upload it to the QR Code Scanner.
Method 1: The Camera App
This is the standard way to scan a QR code on iPhone, and it works without opening any special mode:
Open the Camera app from the Home Screen, Lock Screen, or Control Center
Point the rear camera at the QR code and hold steady for a second
A notification banner appears near the top of the screen with a preview of the link or content
Tap the banner to open it
You can also scan directly from the Lock Screen — swipe to the camera without unlocking your phone, and the same detection works.
Method 2: Control Center's Scan Code Button
If Control Center has a Scan Code button added (it's a default tile on most iOS versions), this is a faster route than opening the full Camera app:
Swipe down from the top-right corner to open Control Center
Tap the QR-shaped Scan Code icon
Point your iPhone at the code and tap the resulting link
If you don't see this button, add it under Settings → Control Center → Scan Code.
Method 3: Checking the Hidden Settings Toggle
Camera-based QR scanning depends on a setting that's on by default but can get switched off:
Open Settings → Camera
Confirm "Scan QR Codes" is enabled
If your Camera app has stopped recognizing codes it used to read fine, this toggle is the first thing to check before assuming the code itself is broken.
Method 4: Scanning From a Screenshot or Saved Photo
The Camera app only works on a code that's physically in front of the lens. If the QR code is already an image — a screenshot, a photo someone texted you, or a saved file — you need a different approach:
Using the Photos app: Open the image, tap the Live Text icon in the bottom-right corner (or tap and hold directly on the QR code), and iOS will offer to open whatever it encodes.
Using the QR Code Scanner: Upload the image directly to the QR Code Scanner from Safari or any browser. This is often faster when you just want to see what a code contains without acting on it immediately, and it works the same way whether the image came from your camera roll or a download.

Scanning Inside Specific Apps
Some apps — WhatsApp, Telegram, Discord, Snapchat — have their own built-in QR scanner separate from the iPhone's Camera app, usually because the code is meant to add a contact or join something inside that app specifically:
WhatsApp: Settings → the QR code icon at the top → Scan Code
Telegram: Settings → Devices → Scan QR Code (for linking a desktop session), or the QR icon on someone's profile to add them as a contact
Discord: Server or friend-request screens sometimes show a "Scan QR Code" option under the add-friend menu
Snapchat: Point the main camera at a Snapcode — Snapchat's camera recognizes its own QR-style codes automatically, no separate scanner needed
If an app has its own scanner, it's usually because the code is meant to do something inside that app (join a chat, add a contact, link a session) that a generic camera scan won't trigger the same way.
Why the Native Camera Sometimes Fails
If pointing your iPhone at a QR code doesn't produce a banner, the most common causes are: the code is too small or too far away, the lighting is poor, the code has low contrast, or the "Scan QR Codes" setting got turned off. If the code itself might be blurry, damaged, or poorly printed rather than a phone-settings issue, see QR Code Not Scanning on iPhone: 6 Fixes for a full troubleshooting walkthrough, or why your QR code won't scan for a more general diagnosis.

FAQ
Do I need an app to scan a QR code on iPhone?
No. Every iPhone on iOS 11 or later scans QR codes natively through the Camera app — no download needed. A third-party scanner app is only useful for niche features like batch scanning or scan history.
How do I scan a QR code on my iPhone without the camera?
If the code is already an image rather than in front of you, open it in Photos and tap the Live Text icon, or upload it to the QR Code Scanner from any browser.
Why won't my iPhone scan a QR code?
Check Settings → Camera → "Scan QR Codes" is turned on first. If it's already enabled, the code itself may be too small, too far away, low-contrast, or damaged — see QR Code Not Scanning on iPhone: 6 Fixes.
How do I scan a QR code from a photo already on my iPhone?
Open the photo in the Photos app and tap the Live Text icon in the corner, or upload the image to the QR Code Scanner for a quick check without leaving your browser.
Where is the QR code scanner on my iPhone?
There isn't a separate scanner app by default — the Camera app itself is the scanner, and Control Center has an optional Scan Code shortcut you can add under Settings → Control Center.
How do you scan a QR code with an iPad?
The same Camera-based method works on any iPad running a recent iPadOS version — open Camera, point it at the code, and tap the resulting banner. If the iPad model doesn't detect it automatically, use the Photos app's Live Text feature on a saved image instead.
