About QR Code Scanner

QR Code Scanner reads a QR code from any image you upload — a screenshot, a photo, a scanned flyer — using the jsQR decoding library, entirely in your browser. The decoded text or link is shown immediately, with a one-click copy button.

This is useful whenever you have an image with a QR code but no phone camera handy, or want to check exactly what a QR code links to before scanning it with your phone.

Checking a link before you trust it

QR codes hide their destination until scanned, which is exactly what makes malicious ones effective — a code stuck over a parking meter or printed on a flyer could point anywhere. Scanning through this tool decodes the text first, without automatically opening any link, so you can read exactly what's encoded and decide for yourself whether it's safe to visit before your phone's camera app takes you straight there.

How the decoding works

This tool uses jsQR, an open-source pure-JavaScript QR decoding library, to analyze the pixel data of your uploaded image directly via the Canvas API's getImageData method. It locates the QR pattern's distinctive corner markers, reads the encoded modules, and applies the same error-correction and decoding steps a phone camera's QR reader would — all without the image ever leaving your browser tab.
