Need to scan a QR code on your Mac? Unlike iPhones, macOS doesn't include a built-in QR code scanner for desktops and laptops. Whether you're using a MacBook Air, MacBook Pro, iMac, or Mac Mini, you'll need a dedicated app to read QR codes.
The good news: Codex QR is a free, native macOS app that scans QR codes in three different ways — using your camera, from image files, or directly from screenshots. It works 100% offline, with no account required and no data sent to any server.
Why macOS Doesn't Have a Built-In QR Scanner
While your iPhone can scan QR codes directly from the Camera app, Apple hasn't brought this feature to macOS. There's no system-level QR scanner on any Mac — not on macOS Sonoma, Sequoia, or any previous version.
This means if someone sends you a QR code in an email, you see one in a PDF document, or you need to scan a printed QR code from your desk, you need a third-party solution. Most people resort to browser-based tools that upload your images to remote servers. There's a better way.
Method 1: Scan QR Codes with Your Mac's Camera
Every MacBook has a built-in camera, and iMacs have one too. With Codex QR, you can use it as a live QR code scanner:
- Open Codex QR and tap Scan QR
- Select the Camera tab
- Hold the QR code in front of your Mac's camera
- The code is decoded instantly — copy, open, or save the result
This works great for scanning QR codes on printed materials, product packaging, business cards, restaurant menus, or any physical item on your desk.
Continuous scanning mode is also available — scan multiple QR codes in a row without stopping. Perfect for inventory, event badges, or batch processing.
Method 2: Scan QR Codes from Image Files
Have a QR code saved as a PNG, JPG, or other image file? Maybe someone sent it via email, Slack, or WhatsApp. Instead of reaching for your phone:
- Open Codex QR and tap Scan QR
- Select the File tab
- Drag and drop the image into the app, or click to browse
- The QR code is decoded instantly
This method also works with QR codes embedded in PDFs, presentations, and documents. Just save or export the image and drop it into Codex QR.
Method 3: Scan QR Codes from Screenshots (The Fastest Way)
This is the feature that makes Codex QR stand out. See a QR code on a website, in a video call, in a PDF, or anywhere on your screen? You don't need to save a screenshot first.
- Open Codex QR and tap Scan QR
- Select the Screenshot tab
- Click Capture — your screen dims and a crosshair appears
- Select the area containing the QR code
- Done — the code is decoded instantly
This is the fastest way to scan a QR code displayed on your Mac screen. No saving, no file management, no switching apps. One click, select, done.
Common use cases for screenshot scanning:
- QR codes in emails and newsletters
- QR codes on websites and web apps
- QR codes shared during Zoom, Teams, or Google Meet calls
- QR codes in PDF documents and presentations
- Two-factor authentication (2FA) setup QR codes
Works on All Macs — 100% Offline
Codex QR is a native SwiftUI app built specifically for macOS. It's not a web wrapper or an Electron app — it's a true Mac-native experience that feels right at home on your system.
It works on:
- MacBook Air (M1, M2, M3, M4)
- MacBook Pro (13", 14", 16")
- iMac, Mac Mini, Mac Studio, Mac Pro
- Both Apple Silicon and Intel Macs
Everything is processed locally on your Mac. No internet connection required, no data uploaded to servers, no account needed. Your WiFi passwords, contact details, and private links stay private.
Not Just Scanning — Generate QR Codes Too
While this guide focuses on scanning, Codex QR is also a full QR code generator for Mac. You can create QR codes for:
- URL — website links
- WiFi — share your network without typing passwords
- vCard — professional contact cards
- Email — pre-filled email with recipient, subject, body
- Phone / SMS — one-tap calling or messaging
- Calendar Event — add events directly
- WhatsApp — start conversations
- Location — GPS coordinates
- Plain Text — any content
All generated QR codes are static and permanent — they work forever, with no expiration and no subscription required. You can also customize colors and export in high resolution.
