QR scanner FAQ
How do I scan a QR code online?
Upload an image that contains a QR code, or allow camera access and point your camera at the code. The scanner reads the QR content in your browser.
Is this QR code scanner private?
Yes. QR images and camera frames are decoded locally in your browser and are not uploaded to NitroClaw servers.
Can I scan a QR code from a screenshot?
Yes. Save the screenshot as an image, upload it to the scanner, and the tool will try to read the QR code from the picture.
What happens if the QR code contains a link?
The decoded link is shown first so you can inspect it. You can copy it or open it after checking the destination.
Why won't my camera scan the QR code?
Camera scanning needs browser permission, HTTPS, and a clear view of the code. If it fails, upload a photo of the QR code instead.
