Although the Windows operating system was updated significantly over the past years.  However, the default Windows Notepad has not been updated in 20 years. If you need a text editor for simple programming tasks, using the vanilla Windows Notepad just does not cut it.

Therefore, we created Notepad3 with all the features that the default Windows Notepad currently lacks. Notepad3 is a fast and light-weight Scintilla-based text editor with syntax highlighting. It has a small memory footprint but is powerful enough to handle most programming jobs without breaking a sweat.

Notepad3 is based on code from the awesome Notepad2 by Florian Balmer and Notepad2-mod by XhmikosR.

Basic Notepad3 Features

Notepad3 has the following features: code folding, bracket matching, automatic indentation, word auto-completion, convert character encoding between various formats (ASCII, UTF-8, and UTF-16), newline format conversion (between DOS (CR/LF), Unix (LF), and Macintosh (CR) formats), multiple undo or redo, bookmarks, and regular expression-based find and replace.
