Locate the HTML file you want to save to text. Right-click the HTML file, select "Open With" and then click "Notepad." The file is opened in Notepad.

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.

You don't need to be online to read a webpage. You can save one, with formatting and images, to local storage and read it later offline.
