Put certificates on the laptop how does it work?

So I would like to apply to a job & also insert my certificate there, how do I do this?

do I have to take a photo of my certificate & then cut it zsm & add this in the email or how do I do it?

Ideally, scan.

Many thanks

Scan the certificate and then save it on the PC and then you can forward the file as an email, for example. It is important that the file is saved as a PDF and that it is sent away.

Thanks very helpful
