A QR code scanner from an image lets you scan a QR code from a picture without a second device. Both iPhone and Android can read a QR code that sits in a photo or screenshot, and there are a few other ways on a computer. This guide shows the quickest methods, what to check before you open the link, and how to fix a code that will not scan.
How to Scan a QR Code From an Image on iPhone
- Open the photo or screenshot in the Photos app.
- Look for a small icon on the QR code, or touch and hold it. On recent versions of iOS, the Photos app can recognize a QR code in an image and show the link or action.
- Tap the result to open it, or touch and hold to see the full link first.
If your iPhone does not show anything, update iOS and try again. As a backup, show the picture on another screen and point the camera at it.
How to Scan a QR Code From a Picture on Android
- Open the image in Google Photos or your gallery app.
- Tap Lens if you see it. Google Lens can read a QR code in an image and offer to open the link.
- If your gallery has no Lens button, open the Google app, tap the camera icon, and choose the screenshot from your library.
Some phone makers build the same feature into their own gallery app. Menus differ between brands and versions, so look for a scan or Lens option when you open the image.
How to Scan a QR Code From an Image on a Computer
- Use your phone. The simplest way is to show the image on your computer screen and scan it with the phone camera.
- Use Google Lens in Chrome. Right-click an image on a web page and choose the Lens option, where it is available.
- Use an online QR decoder. Uploading an image sends it to a third party, so avoid this for private codes, such as boarding passes, tickets or payment codes.
Check the Link Before You Open It
Scam QR codes exist, and a picture of a code can hide where it leads. Before you tap:
- Read the full address that appears. Check that the domain looks right.
- Be careful with codes in unexpected emails, texts or stickers placed over other codes.
- Never enter passwords or payment details on a page you reached from a code you do not trust.
- If the code asks you to install an app, go to the official app store instead.
What to Do If a QR Code in a Picture Will Not Scan
- Use a sharper image. A blurry or tiny code is the most common cause. Take a new screenshot or photo.
- Keep the whole code in the frame. The white border around the code matters, so do not crop it.
- Check the contrast. Light codes on dark backgrounds can fail, and so can codes with an inverted color scheme.
- Remove glare. If you photographed a screen or paper, tilt it to avoid reflections.
- Try another app. One scanner can fail where another works.
Make Your Own QR Code That Scans Easily
If you create codes yourself, use dark code on a light background, keep a clear border, and test the code on two phones. You can make one with our free QR code generator. To learn what is stored inside, read how QR codes work.
Frequently Asked Questions
Can I scan a QR code from a screenshot?
Yes. On a recent iPhone or Android phone you can open the screenshot and use the built-in recognition or Google Lens.
Can I scan a QR code on the same phone that shows it?
Yes, using the Photos app or Lens as described above, since you cannot point the camera at your own screen.
Is it safe to scan any QR code?
Not always. Preview the link, and avoid entering sensitive details on pages you reached from an unknown code.
Why does my phone say no QR code found?
The image may be blurry, cropped or low-contrast. Try a clearer picture with the whole code and its border visible.
