What is the recommended way to embed PDF in HTML?
What does Adobe say itself about it?
In my case, the PDF is generated on the fly, so it can't be uploaded to a third-party solution prior to flushing it.
Probably the best approach is to use the PDF.JS library. It's a pure HTML5/JavaScript renderer for PDF documents without any third-party plugins.
