In what situations would it be more beneficial to convert PDF files to HTML for web viewing, and when is it better to stick with PDF format?

Converting PDF files to HTML for web viewing is more beneficial when you want to make the content easily accessible and searchable on the web. HTML files can be indexed by search engines, making it easier for users to find the information they need. On the other hand, sticking with PDF format may be better when you want to preserve the original formatting and layout of the document, especially if it contains complex graphics or tables that may not translate well to HTML.
