QR Code Scanner & Reader — Scan QR from Screen, Image or PDF

Scan a QR code that's on your computer screen — on a web page, in a picture, in a PDF or in a screenshot. No phone, no app, no uploading. Click the icon (or press Alt+Shift+R): the page dims and every QR code on the screen lights up. Click a code to read it, or drag a box around any part of the page. READS WHAT OTHERS MISS • Every code at once: several QR codes on one page are found together and numbered, so you know which result is which. • Hard codes: small, dense, tilted, damaged and photographed codes; Micro QR and rMQR. • PDFs: tickets, invoices and boarding passes opened in Chrome. • Images: right-click a picture → "Read QR code in this image". It reads the full-size file, so even small thumbnails work. • Files and screenshots: "Open image…" in the menu, or paste a screenshot with Ctrl+V (⌘V on Mac). CLEAR, SAFE RESULTS • Links: see the full address first, then open it in a new tab next to yours. • Wi-Fi: network name, password and security type, with "Copy password". • Email, phone, SMS, contacts, map locations and plain text, each with one-click copy. • Codes that hide javascript:, data:, file: and similar addresses are shown as text with a warning and are never opened. PRIVATE AND FAST • Decoding happens inside your browser. Screenshots and images are never saved or sent anywhere. • No permission warnings on install: the extension sees a page only after you click its icon there. • No sign-up, no subscription, no ads, no redirects through other websites. • Results in a fraction of a second. Changed your mind? Press Esc or "Cancel". • Interface in 15 languages, light and dark theme. GREAT FOR Wi-Fi codes sent as screenshots; QR codes in emails, chats, slides and documents; e-tickets and boarding passes in PDF; codes on product pages and in videos (pause first); checking where a QR code really leads before you open it. Need to make QR codes too? "Make QR codes for your tabs and links" in the menu opens the companion generator.
