There are a couple of reasons why you’d want to convert local or online HTML files to the plain text format (.txt). Maybe you want to move the files to a device that can’t read or display HTML files properly, or maybe, you’d like to turn multiple HTML documents into a single text document for easier archiving, or, you just need the textual information from the documents to use them for work.
While you can now go ahead and use copy and paste to do that, or go through the source code manually, you may quickly realize that it takes some time to do so. Going through the source code is usually not the best option as you may end up copying HTML tags to the new document which are not interpreted in the plain txt file. Depending on the HTML files structure, you may also have issues copying its textual contents when you view it in a browser.
