Notepad3 review
A focused, portable Windows editor with strong text tools and privacy features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Notepad3 is a free, open-source text editor for Windows users who work with code, markup, configuration files, or everyday text. It supports syntax highlighting for more than 55 programming and markup languages, code folding, bookmarks, word auto-completion, rectangular selection, multi-cursor editing, and customizable interface settings. Its 32-bit, 64-bit, and portable editions also make it suitable for users who want a compact editor that can run from a USB drive or optionally replace Windows Notepad.
The pricing model is straightforward: Notepad3 is free, with no paid tiers described. Its capabilities cover both routine editing and more technical text work, including PCRE2 regular-expression find and replace, encoding detection, file-change monitoring, and file history. AES-256 encryption adds a privacy-focused option for protected text, while the integrated MiniPath file-browser plugin and grepWin search tool extend file navigation and search within the Windows environment. These features make Notepad3 a practical fit for users who want more control than a basic text editor without moving to a broader development environment.
Notepad3’s main trade-off is focus. It supports Windows only, and its feature set is narrower than leading alternatives. The published feature set does not clearly establish a dedicated large-file mode or macro recording, so users who require those capabilities should consider another editor. It also does not include AI features. Choose Notepad3 for free, open-source, portable Windows editing with syntax support, search tools, encryption, and file monitoring. Choose an alternative if cross-platform availability, a wider extension ecosystem, or more advanced automation is central to your workflow.
