Windows and macOS have no built-in QR scanner. You do not need to install one: this page scans with your webcam or from any image file, right in the browser, and nothing you scan leaves your machine.
Click the camera button above and allow access when the browser asks. Hold the code to the webcam — printed page or phone screen both work. Laptop webcams focus poorly under 15cm, so hold codes a hand-span away.
Drag any image — screenshot, photo, downloaded file — into the upload box. Desktop screenshots (Win+Shift+S / Cmd+Shift+4) plus upload is the fastest way to scan a code that is on your own screen.
Installed "QR scanner for PC" utilities are mostly adware wrappers around the same open-source decoding this page runs natively. The browser version has no installer, no updates, no permissions beyond the webcam you grant per-session — and you can read exactly what it does, because it is client-side JavaScript.
Open this page, click Start camera scan (or upload a screenshot). Windows has no native scanner app worth installing.
Yes — Safari, Chrome and Firefox on macOS all support webcam scanning here, and image upload works everywhere.
Decoding is local to your browser. The result shows you the link BEFORE you open it — check the domain, exactly as with links in email.
Screenshot that monitor and upload — faster and sharper than pointing a webcam at a screen.
All 20 types free — logos, colours, print-ready files, generated in your browser.
