Frequently Asked Questions

Which browsers are supported?
This tool uses your browser's built-in barcode scanning feature; it works in up-to-date Chrome and Edge.
Why should I check for a QR code in an image?
QR codes unintentionally included in screenshots or photos can direct you or others to unwanted links.
What happens if I open this in Firefox or Safari?
The tool detects that your browser doesn't expose the native barcode-scanning API and shows an unsupported notice instead of failing silently or giving an incomplete result.
Is the image uploaded to a server to be scanned?
No, detection runs through your browser's built-in barcode-scanning API directly on the image you dropped in; nothing is sent anywhere.
Can it find more than one QR code in the same image?
Yes, it returns every QR code it detects in the image, so screenshots containing multiple codes are all decoded and listed.
