Embedding .HTML on a Sharepoint Page

[pjmotley]

I'm trying to display a .HTML file using a sharepoint web part. Is there anyway to do this beyond hosting the .html file and embedding through an iframe?

In the classic way I think you can do this with the content editor webpart.
In modern I think you can do this with the SPFX Script editor webpart:

HTH!
