Where can I download an image file of High Sierra?

I am using High Sierra and have some 32-bit apps that I need to keep. I understand that I could install High Sierra as a virtual machine using Parallels (which I already have for Windows 10). Then I could upgrade to Catalina and use the High Sierra virtual machine when I need to use the 32-bit apps. My question is, what files do I need to have available after I decide to move to Catalina? Is there a single file that I could keep that would allow me to install High Sierra in Parallels?

Download the installer from…

How to upgrade to macOS High Sierra - Apple Support

Use Safari to open the page. Quit the installer when it opens. It will be in the Applications folder, called Install macOS High Sierra.

Okay I double checked. I can drag macOS installer apps directly into this window to install.

Thanks dialabrain. However, as far as I can see, the only option that Parallels gives is to install from an image file. There doesn't seem to be any option to use a link or an installer.
