How do I scan a QR code without an app?

iPhone: Use the built-in Camera app (iOS 12+). Android: Most modern Android cameras scan natively. Alternatively, use Google Lens which is built into many Android phones.

Why is my QR code not scanning?

Most common causes: too much distance or too close (optimal is 15-30 cm), poor lighting, QR code on a reflective surface, or the code is physically damaged. Try adjusting distance and lighting first.

QR Code Scanner: How to Scan QR Codes on Any Device

How to Scan a QR Code on iPhone

How to Scan a QR Code on PC or Mac

Option 1: Use your phone to scan, then airdrop or message the link to your computer.

Option 2: Use an online QR scanner — upload an image of the QR code to a browser-based scanner.

Option 3: Chrome has a built-in QR scanner accessible via right-clicking on any QR code image → Search image with Google Lens.

Troubleshooting QR Codes That Will Not Scan

Too far/close: QR codes need to fill a reasonable portion of the camera frame. Move to 15-30 cm distance.

Poor lighting: QR codes need even lighting. Flash the phone screen at a printed QR or adjust room lighting.

Damaged or distorted QR: If the QR code is torn, wrinkled, or partially obscured, it may not scan. QR codes have error correction built in — up to 30% damage can still be decoded.

Low contrast: Black QR on dark background or white QR on light background may not scan. QR codes need clear contrast between modules and background.

Reflective surfaces: Shiny paper or screens can cause glare that interferes with scanning. Angle slightly to reduce glare.

Screen brightness: When scanning a QR code on a screen, increase the screen brightness to maximum.

QR Code Safety: Beware QRLjacking

Malicious QR codes can redirect to phishing sites. Never scan QR codes from untrusted sources. After scanning, check the URL before tapping to open it.
