Cómo escanear un código QR en cualquier dispositivo

📱

iPhone & iPad

Your iPhone camera has a built-in QR scanner — just open the Camera app and point it at the code. If you have a QR code saved as a photo, use FreeQR's image upload scanner above.

🤖

Android

Most Android phones (Android 9+) scan QR codes natively through the camera or Google Lens. For older devices or saved images, use the FreeQR scanner — no app needed.

💻

Desktop & Laptop

Desktop computers don't have a native QR scanner. Use FreeQR's upload feature: drag and drop a QR code image, paste from clipboard, or browse your files.

🖥️

Chromebook

Chromebooks can scan QR codes through the camera app (Chrome OS 90+). For screenshots or images, use FreeQR's online scanner directly in Chrome — no extension required.

QR Code Not Scanning? Try These Fixes

Camera won't activate

Check browser permissions — look for the camera icon in the address bar.

Code won't scan from a photo

Make sure the QR code is clear, not cropped, and has good contrast.

QR code is blurry

Move closer or zoom in. The code needs to be sharp and well-lit.

"Invalid QR code" error

The code may be damaged, too small, or use low error correction.

Code scans but link doesn't work

The destination URL may have changed or expired (common with dynamic QR codes).

Phone camera doesn't recognize QR codes

Update your OS — QR scanning requires iOS 11+ or Android 9+.

Tip: Still not working? Try uploading a screenshot of the QR code instead of scanning with your camera. Image scanning often works when camera scanning doesn't.

What Is a QR Code and How Does It Work?

A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned, it instantly decodes into text, a URL, contact info, or other data.

QR codes were invented by Denso Wave in 1994 for tracking automotive parts. Today, they're used everywhere — restaurant menus, event tickets, product packaging, business cards, and marketing campaigns.

How scanning works: Your camera captures the QR code pattern. The scanner software identifies the three large squares (finder patterns) to orient the code, then reads the data modules to extract the encoded information. This entire process takes milliseconds and happens locally on your device.
