QR Scanner

How to use it

1. Click Start camera and allow the permission prompt; point the camera at a QR code.
2. The decoded text appears in the result box as soon as a frame is recognized.
3. Prefer a file? Choose a picture and the code is decoded once from the image.
4. Click Copy to take the decoded text, and Stop camera when finished.

Common use cases

• Checking a code before scanning - see where a printed or posted QR code actually leads before opening it on your phone.
• Reading codes from screenshots - decode a QR code captured in an image instead of finding a second device.
• Extracting Wi-Fi or contact payloads - pull the raw text out of a code so you can inspect it.

Why it stays private

Frames are drawn to a canvas on this page and decoded by jsQR in your browser. The video stream is never recorded, stored, or transmitted, and decoding makes no network requests.

FAQ

Q: The camera does not start. What is wrong? A: Permission was denied or the browser has no camera access in this context - some browsers restrict camera access on insecure pages. The message says which happened; the picture file option still works.

Q: My picture contains a code but nothing is found. Why? A: Decoding needs reasonable contrast and a level shot. Blurry, very small, or heavily stylized codes (with logos covering the position markers) may fail. Try a sharper image or a closer crop.

Q: Does it scan barcodes other than QR? A: No - jsQR decodes QR codes specifically. Product barcodes such as EAN or Code128 need a different decoder.
