Limits and Important Notes
How the Current Reader Demo Works
After a file is selected, the browser FileReader converts it to a data URL and assigns that URL to the preview image element.
The Scan action does not access the image data. It reveals a result panel containing a hard-coded OnlineTool.me sample address.
Formula
Current scan result = fixed demonstration URL
Example
Upload a QR image, photograph, or other supported image and press Scan. The current demo always displays https://onlinetool.me/qr-code-generator rather than content extracted from the file.
- Actual QR code detection and decoding are not implemented.
- Webcam scanning and drag-and-drop behavior are not implemented.
- Do not rely on the displayed result as content extracted from your image.
