Notepad saves a file in .txt format. By using Print to PDF and Save As options, you can save it as PDF and HTML in Windows 11/10.

Don’t worry, it’s beyond simple to use. This notepad trick works because of HTML’s “contenteditable” attribute that can turn any part of a web page into an interactive area for editing text.

I use Notepad for writing HTML code, for jotting down quick notes and for “laundering” all kinds of content (capturing the text while getting rid of formatting).

It's not the most useful tool since you can't easily save your work, but this single line of HTML5 code certainly is clever.
