QR Code Reader — Decode QR Codes from Images

No. Decoding happens entirely in your browser using jsQR — the same battle-tested library that powers many web-based scanners. You can verify with your browser's DevTools Network tab: no request is made when you drop an image.

Common causes: low contrast between the QR and its background, motion blur, extreme skew, or reflections on a phone photo. Try cropping tighter around the QR, increasing brightness/contrast in a photo editor, or scanning at a straighter angle.

Not always. QR codes are a common phishing vector precisely because the destination isn't readable by eye. This tool shows you the raw decoded text before you click — always read the URL first, especially if it uses a shortener or an unfamiliar domain.
