Someone texts you a screenshot containing a QR code. Or you saved a QR code from a website for later. Or a PDF attachment includes one linking to a signup page. The QR code is sitting on your Mac screen as an image, and the natural instinct is to "scan" it — but how? Pointing your phone camera at your computer monitor is awkward, produces glare, and opens the link on the wrong device. macOS provides no built-in way to decode a QR code from an image or screenshot.
No Native QR Decoder on macOS
iPhones have QR scanning built into the Camera app. macOS has nothing equivalent. You can't right-click a QR code image in Finder and choose "Decode." Preview won't extract a URL from a QR code. Safari doesn't recognize QR codes in web pages. If the QR code is already on your Mac screen, Apple's ecosystem expects you to use a different device to read it — which makes no sense when you want the result on the same computer.
Online QR decoders exist, but they require uploading your image to a third-party server. For QR codes containing sensitive information — Wi-Fi passwords, authentication tokens, private URLs — uploading to a random website is a non-starter.
Decode QR Codes Right on Your Screen
Optic includes a QR code scanner that works on anything visible on your display. Open the screenshot or image containing the QR code, activate Optic from the menu bar, and drag a selection around the code. The decoded content — URL, text, credentials, whatever the code encodes — appears on your Mac immediately.
Event Tickets and Boarding Passes
QR codes on email confirmations, forwarded tickets, and saved boarding passes are common. Decode them on your Mac to verify the content, open the linked page, or save the encoded information — all without switching to your phone.
Wi-Fi and Authentication Codes
QR codes encoding Wi-Fi credentials or two-factor setup URIs contain sensitive data. Optic decodes them locally on your device — no upload to external servers, no exposure of your credentials to third-party services.
Saved in Capture History
Every decoded QR code is saved in Optic's menu bar history alongside your text captures. Need the Wi-Fi password from a QR code you scanned last week? Scroll back through your captures instead of finding and re-scanning the original image.
