Saving screenshot file as vector image

We are using many screenshots in our blogs. We use licensed copy of SnagIt (2022.1.4) to take the screenshot. We want to save the screenshots in vector format so that the HD quality screenshots can be included in blogs that can be viewed of bigger screens as well. However, we do not see any such option. Using PNG is ok for screenshots added only to manuals.

If not vector format, what is the best practice to create HD quality screenshots that do not distort?
