What is Notepad3?
Notepad3 is a Windows text editor for working on scripts, configuration files and everyday plain text. Built on Scintilla and maintained by Rizonesoft, it adds syntax highlighting for languages including Python, C++, PowerShell, JavaScript and SQL. Code folding, bracket matching and automatic indentation help when reading or changing structured files.
Regular-expression find and replace handles pattern-based changes, while bookmarks help you return to particular lines. Character-encoding conversion supports ASCII, UTF-8 and UTF-16, and line-ending conversion handles DOS, Unix and Macintosh formats.
This entry links to the publisher's 64-bit Windows installer for version 7.26.602.1. Rizonesoft also offers separate 32-bit and portable packages. The installer can place Notepad3 alongside Windows Notepad or replace it through the publisher's registry-based integration option.
Notepad3 focuses on editing rather than a full development environment: it does not provide IDE-style debugging or project-management tools. Choose it for text and code edits, not as a substitute for an integrated debugger and project workspace.
What it offers
- Syntax highlighting for programming, scripting and configuration formats, including Python, C++, PowerShell, JSON and SQL.
- Code folding, bracket matching, automatic indentation and word auto-completion.
- Regular-expression find and replace, line bookmarks and multiple undo/redo.
- Convert character encodings and switch between DOS, Unix and Macintosh line endings.
- Install alongside Windows Notepad or use the publisher's optional replacement integration; a separate portable edition is available.
Good to know
- Does not include IDE-style debugging or project-management tools.
- The linked package is the x64 installer, not the separate 32-bit or portable edition.
