OK, you can use Notepad for copying plain text from a web page or from other document without getting all formatting from the original source. Opening Notepad, doing a paste, followed by a SELECT-ALL, and then a copy paste to another application, all these are inconvenient and a time consuming (at least for me) process.
PureText is a tiny application for Windows that allows you to paste text to any application without formatting by simply adding a new Windows hot-key (default is WINDOWS+V).After running PureText.exe, you will see a "PT" tray icon appear near the clock on your task bar. You can click on this icon to remove formatting from the text that is currently on the clipboard. You can right-click on the icon to display a menu with more options.
PureText only removes rich formatting from text. This includes the font face, font style (bold, italics, etc.), font color, paragraph styles (left/right/center aligned), margins, character spacing, bullets, subscript, superscript, tables, charts, pictures, embedded objects, etc.
However, it does not modify the actual text. It will not remove or fix new-lines, carriage returns, tabs, or other white-space. It will not fix word-wrap or clean up your paragraphs. If you copy the source code of a web page to the clipboard, it is not going to remove all the HTML tags. If you copy text from an actual web page (not the source of the page), it will remove the formatting.
