So, I need to add
https://www.rapidtables.com/tools/notepad.html in my website and I need to remove the header of their website.
Is there any way?

Answer

if you do iframedoc = document.getElementById("my_iframe").contentDocument; you can do everything you can do with document. The problem is that if you dont own the page you are embedding, your edit will be blocked by your browser because of cors (https://en.wikipedia.org/wiki/Cross-origin_resource_sharing). To bypass this you need to fetch the page with your backend server and pass the file to your javascript.
