About Notepad++
Notepad++ is a free, open-source code editor for Windows written entirely in C++ using pure Win32 API. At just 4MB installed, it's the most lightweight code editor with real programming features — syntax highlighting for 80+ languages, tabbed editing, multi-view split screen, macro recording, and a plugin ecosystem via Plugin Admin. Notepad++ launches instantly, uses minimal RAM, and handles everyday coding, log file inspection, and text manipulation tasks that don't warrant opening a full IDE. It's been a Windows developer staple since 2003 and remains the default recommendation for anyone who needs something between basic Notepad and a full development environment.
