QR Code Scanner

Decode a QR code from an image file with the jsQR engine — camera-free, fully local.

About this tool

Upload a photo or screenshot containing a QR code and read its content locally with the jsQR engine — the counterpart to the QR Code Generator, with the same no-upload promise.

How to use the QR Code Scanner tool

  1. Choose the image. A clear, straight-on photo or screenshot works best.
  2. Scan. jsQR examines the pixels locally.
  3. Copy the content. The decoded text or URL.

Supported formats

Input

  • Plain text or file input

Output

  • Converted or analysed output

Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.

Frequently asked questions

Why not my camera?

Camera access needs permissions and varies by device; file-based scanning is predictable. You can screenshot a QR and scan that.

Which codes are supported?

Standard QR codes; other 2D formats are not.

Why did my photo fail?

Blur, glare or skew defeat the detector — the error says so rather than guessing.
