How to Scan a QR Code on PC or Mac Without a Phone
We often encounter QR codes on our desktop monitors—in emails, PDF documents, invoices, or websites. Traditionally, you had to pull out your smartphone, open the camera app, and scan your screen.
With Imagerry's QR Code Decoder, you can scan QR codes directly on your computer in 3 seconds:
Win + Shift + S
Snip the QR code on your screen, then switch to this tab and press Ctrl + V to decode it instantly.
Cmd + Ctrl + Shift + 4
Copy the screen area directly to your clipboard, then press Cmd + V on this page.
Extract WiFi Passwords Directly from QR Codes
When you share a WiFi network from an Android or iPhone device, it creates a QR code containing an encoded string formatted like WIFI:S:MyNetwork;T:WPA;P:SecretPassword;;.
Imagerry automatically parses this string, separating the Network Name (SSID), Security Encryption, and provides a 1-click button to copy the raw password so you can connect your laptop without typing complicated keys manually.
Why Privacy Matters for QR Decoding
Many online QR code readers require you to upload your image to their remote server. This presents a serious security vulnerability when scanning:
- Two-Factor Authentication (2FA) Seed Keys: Authenticator app setup QR codes contain your private OTP secret keys.
- Personal Contact vCards: Full names, private phone numbers, physical addresses, and personal email accounts.
- Event Tickets & Boarding Passes: Unique digital tokens and gate access codes.
- WiFi Credentials: Your home or office network password.
Imagerry guarantees 100% client-side execution. The computer vision scanning algorithm runs directly in your local browser sandbox. Your images and extracted data never touch the internet.

Yes, 100% safe. Imagerry processes computer vision decoding entirely in client-side JavaScript within your browser memory. Your image and decoded payload are never uploaded to or stored on any external server.
What types of QR codes can this decoder read?
Imagerry automatically identifies and formats: website URLs, WiFi network configurations (SSID, security type, and password), vCard and MeCard contact details, email links (mailto:), phone numbers, SMS messages, cryptocurrency addresses (Bitcoin, Ethereum), and raw plain text.
Can I scan a QR code from a phone screenshot or image gallery?
Yes! Simply save or AirDrop the screenshot to your computer, or open Imagerry on your phone's browser and choose the image from your photo library to decode it instantly.
Why is my QR code not being detected?
Make sure the QR code is clearly focused, not cropped or skewed at an extreme angle, and has adequate contrast against its background. If taking a screenshot, make sure to include the three corner square locator marks.
