More about the QR Code Scanner
A QR code printed on a flyer or embedded in an email doesn't reveal where it actually leads until it's scanned, and scanning it directly with a phone means committing to whatever page or action it triggers before actually knowing what that is, which matters when the code showed up somewhere less than trustworthy. This tool scans and decodes a QR code from an uploaded image or a live webcam feed, showing the actual text or URL hidden inside instantly rather than requiring a phone's camera app to commit to opening it. Useful for checking a QR code's actual destination before scanning it with a phone and getting redirected somewhere unexpected, decoding a QR code from a screenshot or a saved image without a phone on hand, or reading a code live through a webcam during a presentation or a meeting.
Scan and decode QR codes from images or webcam with instant text output. The QR Code Scanner is one of 900+ free developer tools on Toolblip - all open to use without a signup.

What image formats does the QR Code Scanner support?
The QR Code Scanner works with common web image formats including PNG, JPEG, WebP, GIF, and SVG.
