How to scan a QR code from an image on your computer
You don't need a phone to read a QR code you're already looking at on screen. QR Studio decodes from an image file, a drag-and-drop, a clipboard paste, a right-click on any image on a page, or a capture of the whole visible tab — all locally, with no upload.
The usual way
- 1Take a screenshot of the code or save the image to your computer.
- 2Search for an online QR decoder and open one of the results.
- 3Upload your image to their server and wait for it to come back with the decoded text.
- 4Copy the result, and hope the destination link is safe to open.
Where that falls short
- Uploading is the problem: the image goes to a third party, and a QR code you found in an email or an unfamiliar document is exactly the kind of thing you don't want to hand over — or to have logged against your IP address.
- Most online decoders take a file upload and nothing else. There is no right-click on an image, no clipboard paste, and no way to scan a code that's embedded somewhere on the page you're reading.
With QR Studio
- 1Press Alt+Shift+S to open the QR Studio scanner, or right-click the image directly and choose to scan it.
- 2Drop in the image, paste a screenshot from the clipboard, or pick a file — you can also capture the whole visible page and let QR Studio locate the code in it.
- 3Read the decoded value, which QR Studio parses into its actual type (a link, a contact, a Wi-Fi network), then copy it or open it once you've checked where it goes.
Free, offline, and the code you get is static — it can't expire or be redirected later.
