A simple web app to optimize the QR code of the Digital COVID-19 Certificate.
The DCC QR code is quite dense: this could cause issues during the scanning in the verification process (especially when printed).
This application takes a QR code as an image file or by directly scanning it with a camera and returns a new one that is easier to read."
Nothing in the content is touched and stored in the server, this application only re-encodes the QR code with a lower error correction.
