What this QR code scanner reads

🔗 Links and URLs

Decode any website link in a QR code. The scanner shows you the full web address and lets you open it with a tap, so you always see where it leads first.

📶 Wi-Fi networks

Scan a Wi-Fi QR code to reveal the network name and password, then copy either one instantly instead of typing it by hand.

👤 Contacts (vCard)

Read a contact QR code to see the name, phone, email, and company, then save it straight to your contacts as a .vcf file.

✉️ Email, phone, and SMS

Turn a QR code into a ready-to-send email, a tap-to-call number, or a prefilled text message.

📍 Locations and events

Open map coordinates in your maps app, or save a calendar event that is encoded in the QR code.

📝 Plain text

Reveal any message, note, or code stored inside the QR and copy it in one tap.

Built-in link safety

QR code scams (sometimes called "quishing") hide a harmful link behind a normal looking code. This scanner never opens a link on its own. It shows you the full destination address first and waits for you to decide, so you can spot a suspicious site before you visit it.

Nothing leaves your device

QR decoding happens right in your browser. Your camera feed and any image you upload are read on your own device and are never sent to a server.

Scan a QR code from a screenshot or image

Camera scanning

Tap Start Camera, allow access, and point your phone or webcam at the QR code. It decodes in real time, and the torch button helps in low light.

Upload an image

Got a QR code in a screenshot, an email, or a saved photo? Switch to Upload Image and the scanner reads it from the file. Supports JPG, PNG, GIF, and WebP.
