Covid-19 GreenPass Decoder

Very important note

This tool decodes the information contained in a Covid-19 GreenPass. A full description of all GreenPass data is available in Technical Specifications for EU Digital COVID Certificates (PDF file), version 1.3.0, on the eHealth Network. If you don't want to use a real QR code, you can test it with the images from the official test repo.
IT DOES NOT validate or generate new certificates. IT DOES NOT upload your data anywhere, all the processing is done locally in your browser.
