QR code scanner online - read a code from an image or camera

Decoding happens in your browser. If the browser has a built-in code detector (BarcodeDetector), the tool uses it; otherwise it falls back to the jsQR library, which tries the image at several scales. The content is recognised and split into clear fields:

• Links - with domain analysis and warnings,
• Wi-Fi - network name, password and security type,
• vCard contacts - name, company, phone, email, address,
• Polish bank transfer QR codes (ZBP standard) - recipient, account, amount in PLN and transfer title,
• Email, SMS, phone, GPS location and plain text.

“Quishing” is QR phishing: a fake code stuck on a parking meter, printed on a flyer or sent by email leads to a page that steals logins or payments. This scanner never opens links automatically. It shows the target domain and warns you when the address is not encrypted (http), is a bare IP number, contains international characters (xn--) or has login details placed before the domain. Addresses such as javascript: or data: do not get an open button at all. Always check that the domain is the one you expect, and never log in to your bank through a QR link - type the address yourself.

A QR code simply stores text - its beginning decides what a phone does with it. The scanner checks the content against these patterns:

Anything else is shown as plain text. For bank transfers, an amount stored in grosz (e.g. 012345) is converted to złoty (123.45 PLN) - compare it with your invoice before approving the payment in your banking app. You can upload several files at once; one code is read from each image.

• The photo is blurry or overexposed, or the code is tiny in the frame - crop the picture down to the code.
• The code is damaged or covered beyond what its error correction can fix.
• The code has no “quiet zone” - the light margin around it.
• The image is huge - the tool scales it down, but a fresh close-up photo sometimes helps.
• It is not a QR code but another kind, such as an EAN barcode - this scanner reads QR codes only.
