Use a PDF to image converter

There are both free and paid options for converting PDFs into image files.

Adobe allows you to convert two files per day at a high quality for free without needing to create an account. Here is the link: https://www.adobe.com/au/acrobat/online/pdf-to-jpg.html

You can also do a web search for 'PDF to image converter' to see other options.

Screenshot

Another option is to use your computer's snipping or screenshot tool to capture the full page of the PDF as an image.
