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.

Basic Notepad3 Features

Furthermore, 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.

Supported Languages

Previously we mentioned that Notepad3 can handle almost any programming job and we are not lying. Just take a look at the list of supported programming languages below and spot your favorite.

It offers syntax highlighting support for ASP, assembly language, AutoHotkey, AutoIt3, AviSynth, Bash, BAT, C, C++, C#, CMake, CoffeeScript, Common Gateway Interface (CGI), Cascading Style Sheets (CSS), DIFF, HTML, INF, INI, Inno Setup, Java, JavaScript, LaTeX, Lua, Markdown, NSIS, Pascal, Perl, PHP, Python, REG, Ruby, SQL, Tcl, Visual Basic (VB), VBScript, VHDL scripts, XHTML, XML, YAML and improved support for NFO ANSI art.

Download Notepad3

Notepad3 comes in two flavors. A setup for installing Notepad3 to your computer and optionally replacing the default Windows Notepad. And a portable version for running it straight from a memory stick or portable hard drive. Just download which ever you prefer.

Installing Notepad3

Notepad3 is available for PCs running Windows XP (SP3), Vista, 7, 8, and 10. Simply download the installer below and run it to start the installation process. It supports replacing the default Windows Notepad using a clean, unobtrusive registry-based method, but can also be installed along-side Windows Notepad.

      Sorry about this. I fixed it and it is working on Windows XP now. Will have the new release up in a few hours. 🙂

    The most recent version (386) broke the ALT+W shortcut (“Strip Trailing Blanks”). Trailing tabs are not removed anymore, but in my opinion they should be covered by that as well (as it was the case in Notepad2 and in Notepad3 until version 350). Thanks for reverting that change, or making it an option otherwise!

    Also please can you make in text hyperlinks and e-mail adresses clickable?
    Thank you

    Please label the two Input fields in the encryption dialog for Screen Readers like in the search and replace dialog.

      I’ll make the changes and it will be available in the next update.

    Is it just me, or the “Notepad3 Setup – Build 350 (64 and 32 Bit)” links to a corrupted file. I did it three times already. Here are the checksums:

    Hi, i like see an more updated notepad2, heh notepad3 is a good name choise 🙂
    I wish see really new features on it, (without make this bloated ofcourse heh)
    * Translations support.
    * Tabbed MDI (multiple document interface), PMDI (pseudo multi-window interface) modes
    An example with this features is AkelPad

    i don’t understand why if notepad2 is using scintilla not have this features while scite and others scintilla based if.

    How do you do?
    I’m quite happy with it, Notepad3 that is, + it seems to me you’ve got your work cut out with all the “it hasn’t got this, it hasn’t got that” from seemingly all angles. So, I ask nothing of you, make no request or appeal + am happy to make do with what there is, it could be a generation thing? When I were a lad……………………

      1. rachman

        Seems he talked about tabbed interface, like Notepad++

        1. Rizonesoft Post author

          Thanks. We will not be working on tabbed interface soon. But maybe later.

    I’m using dark colors: Default Style=font:Lucida Console; size:10; fore:#FFFFFF; back:#333333

    It would be very nice to have an option to set the color for the cursor too in the Notepad3.ini.

    Thanks in advance

    Would you please update it with larger icon in toolbar? I’m using 125 scaling so in HiDPI res (mine 1080p) the toolbar is quite small. Perhaps also with minimal/material design, monochrome icon (like in Android, iOS app, Microsoft Edge, etc).

  9. webfork

    Where’s the source code posted? Also could you setup a Github (or similar) site for this? I think that would make it a bit easier to track issues.

    I just came across the notepad3 through a post I saw on the notpad2-mod website.

    One thing I really appreciate here over the notepad2-mod is that changes to new versions are listed 🙂

    Have been using notepad2 and the -mod for years now, but have always missed out on couple of features I had with Emeditor (before it became paid software and bulky). Not sure you would find this useful enough to take a look, but would help me and maybe others if you could consider these:

    This Emeditor that I had, had this one feature I value a lot. As with notepad3, when I search for a text within the file, it, highlights all instances of that word and the cursor moves to the first found instance. On pressing F3 or Find next, it still keeps everything highlighted but moves to the next instance. The Status bar gives information of the number of found items. The advantage is that even without pressing F3 or Find next, the user can just scroll down and see all highlighted items. A menu command allows to remove highlights.

    Also, would it be possible to highlight and make clickable all urls and email addresses.

    Emeditor has got this small but very useful thing. If a file has already been saved, the Save button icon and option under file are not clickable and are greyed out.

    Would really like to know if you think they are useful and possibly implementable.

      Just give me a week max to work on this. Check back next week for an update.

    Compared to Notepad2-mod

    Missing questions marks on search and replace windows. Questions marks give all the options for both Regular expression search and Transform backslashes.

    Wildcard search is missing completely.

  12. Bob Smith

    One item I wish Notepad2 had, and now Notepad3, …is a ‘Select All’ toolbar button.
    Not exactly a show stopper without it, just an added convenience if it was available.

    Also wondering since I presently have Notepad2 installed as my Windows notepad replacement,
    do I need to uninstall it first, then install Notepad3 as the Windows notepad replacement, or can
    I just run the Notepad3 setup exe with the install taking care of making it the system default Notepad?

    Thank You Sir.

    1. Rizonesoft Post author

      Better to uninstall Notepad2 before installing Notepad3 because it uses another method for replacing the Windows Notepad. Try Edit -> Select All!

    Getting this error while opening the file… I tried downloading it with and without IDM.

    1. Rizonesoft Post author

      Ok, its fixed. There was a problem in my download system when downloading exes. I created a zip file with the exe in it. Let me know if its working for you now please.
