QR Code Scanner

Not every QR code is in front of a phone camera when you need to read it: a code sitting in a screenshot, a PDF, an emailed flyer, or a photo already saved to your device still needs decoding, and this tool does exactly that: upload an image containing a QR code and it's decoded instantly, entirely in your browser.

Drop in a photo or screenshot and the tool locates the QR code, highlights exactly where it found it on the image, and shows the decoded content below: plain text, a URL you can open directly, an email address, a phone number, Wi-Fi network details, or a vCard contact card. It automatically recognizes which of these the code contains based on its standard prefix (like "https://" for a link or "BEGIN:VCARD" for a contact card) and labels it accordingly, so you don't have to guess what you're looking at.

Decoding works the same way a phone camera's built-in scanner does, analyzing the pattern of black and white squares to reconstruct the encoded data, except it happens against the pixels of an uploaded image rather than a live camera feed, using the open-source jsQR library running as plain JavaScript. If a code can't be found (a blurry photo, a code that's cut off, poor lighting), the tool says so plainly and suggests trying a clearer image, rather than failing silently.

Every step, from reading the uploaded file and decoding the QR pattern to displaying the result, happens locally on your device. The image and whatever the code decodes to are never uploaded, transmitted, logged, or stored anywhere, even if the decoded content is a link or contact details.
