How to Scan a QR Code on iPhone and Android (No App Needed)

The short answer

On nearly every phone made in the last several years, you scan a QR code with the built-in camera app. You do not need to download a separate scanner. Open the camera, point it at the code, and tap the link that pops up. The longer guide below covers each platform, the few older phones that need help, and what to do when a code stubbornly will not scan.

How to scan a QR code on an iPhone

Every iPhone running iOS 11 or later, which covers essentially all iPhones still in use, can scan QR codes straight from the Camera app.

1. Open the Camera app from the home screen or lock screen.
2. Point the rear camera at the QR code so the whole code sits inside the frame.
3. Hold steady for a moment. A yellow notification banner appears at the top of the screen.
4. Tap that banner to open the link, WiFi prompt, or contact card the code contains.

If nothing appears, open Settings > Camera and make sure Scan QR Codes is turned on. iPhones also include a dedicated Code Scanner in Control Center you can add for one-tap access.

How to scan a QR code on Android

Most Android phones from the last few years scan QR codes directly in the camera too, though the exact path varies by manufacturer.

1. Open the Camera app.
2. Point it at the code and wait for a link or pop-up to appear.
3. Tap the link to open it.

If your camera does not detect the code, you have two reliable built-in options:

• Google Lens: open it from the camera, the search bar, or the Google app, point it at the code, and tap the result. Lens is built into most Android phones and reads QR codes even when the plain camera does not.
• Quick Settings tile: swipe down from the top of the screen and look for a Scan QR code tile. Many Android skins include one.

How to scan a QR code from a photo or screenshot

Sometimes the code is already on your screen, for example in an email, or saved as a screenshot. You cannot point your camera at your own screen easily, so use these instead:

• iPhone: open the image in Photos, then tap the Live Text or Lookup icon, or long-press the code to get an Open Link option.
• Android: open the screenshot, then use Google Lens (often a button right in the screenshot preview or in Google Photos) to read the code.

What about older phones?

If you have an older device whose camera will not detect codes, install a free, reputable QR scanner app from your official app store. Choose one with strong reviews and avoid apps that demand excessive permissions, since a scanner only needs the camera. Once installed, open the app and point it at the code.

When a QR code will not scan

If a code refuses to open, the problem is almost always physical, not your phone. Run through this checklist:

• Get the lighting right. Glare and deep shadow both confuse the camera. Tilt the code or move to even light.
• Mind the distance. Too close and the camera cannot focus, too far and the squares blur together. Start about an arm's length away and adjust.
• Fill the frame. Make sure the entire code, including its white margin, is visible.
• Check for damage. A creased, smudged, or partially covered code may be unreadable. The code's error correction tolerates small damage but not a missing corner.
• Confirm the code is big enough. A code printed too small for the scanning distance simply will not resolve. Whoever made it should follow our QR code size for print guide.

If you are the one creating codes that people struggle to scan, our QR code best practices covers the design and placement rules that keep scan rates high.

Is it safe to scan QR codes?

Scanning a code is as safe as the link behind it. A code is just an encoded URL, so treat it like any link you tap online. Most phones show you the destination before opening it, so glance at the domain first and be cautious with codes in untrusted public places, where a sticker could have been swapped. Codes from a known business, menu, or product are routinely safe.

Want to make your own QR code?

Reading codes is free and built into your phone. Making them is just as easy. Head to the QRmaker generator to create a free static code in seconds, no signup required. If you want a dynamic code you can edit after printing, with scan analytics, check the pricing page or create an account to get started.
