Is the image uploaded?

No. Decoding happens locally — Canvas reads the pixels and jsQR analyses them in your browser. The image and decoded data never leave the page.

What if the decoder can't find a QR code?

Make sure the QR fills a reasonable portion of the image, is in focus, and has good contrast. Heavily blurred or tilted codes may need a clearer source.

Can it decode QR codes inside other content (memes, screenshots)?

Often yes — jsQR scans the whole image. If multiple codes are present it returns the first one it finds.

Does it support special QR types like Wi-Fi or vCard?

The decoded text is returned as-is. For Wi-Fi or vCard codes you'll see the raw payload (e.g. WIFI:T:WPA;S:Name;P:secret;;) which you can paste into another tool to act on.

QR Code Decoder

Drop or pick an image that contains a QR code (a screenshot, a photo of a printed code, a downloaded share image) and the tool returns the encoded text — a URL, Wi-Fi credentials, a vCard, plain text, whatever was in the code. Powered by jsQR, runs entirely in your browser via Canvas, so the image and decoded contents never leave your device.

Guides on this topic

Why your QR code won't scan on some phones It works on your desk and fails on the poster. QR codes are read by finding three corner squares in a clean margin, and most scanning failures are a margin, a contrast or a size problem rather than anything wrong with the data inside.
