What image formats are supported?

PNG, JPG/JPEG, and WebP are all supported. Make sure the QR code is clearly visible and not blurred.

Can I scan a QR code from a screenshot?

Yes — take a screenshot of the QR code, upload it here, and the decoder will extract the content automatically.

Why can't the scanner read my QR code?

Common causes: the image is too blurry, the QR code is too small in the frame, or the image has very low contrast. Try cropping the image so the QR code fills most of the frame.

Is my image sent to a server?

No. QR code decoding runs entirely in your browser using JavaScript. Your image never leaves your device.

Can it decode QR codes from PDFs?

Take a screenshot of the PDF page containing the QR code and upload that screenshot. Direct PDF upload is not yet supported.

What types of content can a QR code contain?

QR codes can encode URLs, plain text, contact cards (vCard), email addresses, phone numbers, WiFi credentials, and more.

Is there a way to scan QR codes using my camera?

Your phone's built-in camera app can scan QR codes directly. For desktop use without a camera, uploading a screenshot is the easiest approach.

Can I use this to check if a QR code is safe before scanning?

Yes — decoding the QR code here lets you see the URL or content before following it with your phone, which helps you identify phishing or malicious links.
