QR code reader
What QR decoding returns
Upload a sharp photo of a matrix barcode and read the embedded payload—often WIFI: setups, vCard contacts, plain URLs, or opaque binary chunks depending on the generator. Blur, glare, or low contrast blocks decoding; reshoot square-on under diffuse light.
Safety
Treat decoded URLs like untrusted hyperlinks—verify domain visually before visiting, especially outdoor stickers. Pair with Safe URL checker when unsure.
