QR Code Scanner

A scanner that understands the content, not just the raw text

Most QR code readers just hand you the decoded text and leave you to figure out whether it's a Wi-Fi network, a contact, or a link. This scanner goes further: it recognizes the structure of every common format (a Wi-Fi network, a vCard or MeCard contact, a PIX copy-and-paste code, a calendar event, geographic coordinates, a phone number, an SMS, an email, and a link) and builds a ready action for each one, like downloading the contact as a .vcf file, adding the event to your calendar, or copying the Wi-Fi password. The camera decodes continuously while you point your phone at a code, trying multiple scales and rotations so it can catch even a small, rotated, or low-contrast QR code, and the same photo can hold more than one code, all of them get detected. No image ever leaves your browser, the whole decoding pipeline runs locally.

From the camera to an interpreted result

1. Choose to scan with your camera (grant access when the browser asks) or upload an image, either by dragging a file, picking one from the file browser, or pasting a screenshot.
2. Point the camera at the QR code inside the framing guide, or wait for the uploaded image to process. If the scene has more than one code, all of them show up in a list so you can pick which one to view.
3. The decoded content already comes interpreted: a link shows its domain and risk level, a Wi-Fi network shows a password ready to copy, a PIX code shows the amount and whether the code's checksum is valid, and so on.
