How do I force files to open in the browser instea

Question

Is there a way to force PDF files to open in the browser when the option "Display PDF in browser" is unchecked?

I tried using the embed tag and an iframe, but it only works when that option is checked.

What can I do?

Answer 1

Either use

<embed src="file.pdf" />

if embedding is an option or my new plugin, PIFF: https://github.com/terrasoftlabs/piff
