QR Code Scanner Online Free — No App Needed

Why Use a Browser-Based QR Scanner?

Most people reach for a dedicated QR scanner app when they need to read a code. But your phone already has a browser that can do the same thing — without installing anything, without creating an account, and without giving an app access to your camera roll, contacts, or location data.

Browser-based QR scanning uses the same camera access as a native app, but the processing happens entirely in your browser tab using JavaScript. When you close the tab, the data is gone. No history stored on a server, no analytics on what you scanned.

MiOffice's QR scanner uses the jsQR library to decode QR codes in real-time from your camera feed or from uploaded images. It supports all standard QR code types and works on any device with a modern browser.

100% Client-Side Privacy

MiOffice processes QR codes entirely in your browser using JavaScript. Your camera feed is never streamed to a server. Uploaded images are decoded locally and discarded when you close the tab. There is no account, no history, and no tracking of what you scan. This makes it safe for scanning sensitive codes like boarding passes, medical QR codes, and payment links.
