Although the Windows operating system was updated significantly over the past years.ย  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. Enter Notepad3!

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, D Source Script, Go Source Script, JSON, Makefiles, MATLAB, Nim Source Code, Power Shell Script, Resource Script, Shell Script and improved support for NFO ANSI art.

    Thanks for this, just discovered Notepad3, and switched from Notepad2 Mod.
    Noticed one minor issue though, the “eolfilled” parameter has no effect for the “Registry files” scheme.Registry files look the same with our without the “eolfilled” argument.
    Not sure if other schemes are also affected, I didn’t test them all, but “eolfilled” does work for batch files though.

    This was working in Notepad2-mod for registry files.

        Hello coch,
        The first short answer is: “Works as expected”, but if you follow the links above, you will see that the complete answer is much more nuanced !

          Thanks a lot, much appreciated, and as a bonus I got to learn a little about the functioning of Notepad3 (I had no idea what a lexer was before reading the github). That said, I really like the enhanced “lexer” for the registry editor. I understand a workaround would be to use configuration files like it was in Notepad2-mod to get the eolfilled functionality back, but I would lose the other registry files-specific enhancements, which I really like (especially the “GUID” formatting to make it easier to spot those in registry files). Now my only issue is deciding which of the two choices I like best considering advantages and limitations of each one ๐Ÿ™‚

          Thanks again!

        Thanks for replying to me, and I will be reading on development on
        I tested the new versions and and did have any visible problems with them, although the “eolfilled” parameter only appears to be enabled for “Added Keys”, is that right?
        I’d be interested in “eolfilled” also be enabled for Comments in registry files, unless that causes issues. You bring a good point in about registry files having comments right after Added Keys, and not sure how this would be dealt with (in Notepad2-mod, using the Configuration files lexer the “Added Keys” eolfilled argument would prevail when adding a comment on the same line).

    Dear Mr. Derick Payne…

    Is there any version of Notepad3_x_3.18.113.828.exe that replace Notepad to download…?

      1. Azmin

        Thank you so much for your information. ๐Ÿ™‚

        It’s good when Notepad3 had a integration installer that replace Notepad.

    I tried using Notepad3 and quickly found that clear-button in toolbar doesn’t work reliably. I have to copy text before the clear-button is enabled and can be used after selecting text. Is this program recommended as a stable alternative to Notepad2?

    1. craigo-

      Are you referring to the ‘Cut’ toolbar icon? I’m not currently able to reproduce your issue…Please try the latest release and let us know if you still have a problem.

  5. Jay

    Could you please add “Favorites” to the top menu, along with view, settings, help, etc. It would be so much quicker and easier to get to. Similar to that found in “Win32pad”. Wonderful program BTW!

    1. craigo-

      Favorites icons are present in Notepad3’s default as-shipped toolbar. You can add and remove toolbar buttons to how you want by clicking ‘Settings’ -> ‘Customize Toolbar…’

  6. LTK

    Is there a plan to support changing the interface language of Notepad 3?

    Hello there.
    Been using Notepad2-mod for many years, no prob. Decided to try Notepad3 this September (or August). Very similar to Notepad2, all was working great. Til I decided to update it a few days ago. While i’m not 100% sure this wasn’t happening with the older, “September” version, too, but now i started to notice flashing lines. Will try to explain: take a wall of text without spaces so you can see it more clearly, and then just look at the window: you will see random lines flashing (and the bottom bar, i.e. Ln, Col, size, etc…), every 2-3 seconds or so. It much much worse when you try to select part of that text – all lines will flash like crazy (and bottom bar too)!! Back to Notepad2-mod, where only bottom toolbar will, sometimes, flash. Default config in both cases by the way. Hope you can solve it soon ๐Ÿ™‚
    Keep it up.

      We are aware of the bug. We recently introduced an experimental ‘hyperlink hotspot’ feature that caused a few issues. But this is expected with any new feature. I apologize for not testing it properly before releasing. However, you can expect a new version on the 23rd with most if not all the bugs sorted out. Thank you for your support. ๐Ÿ™‚

      1. Alex

        Many thanks for so fast reply ๐Ÿ˜€
        Yes, that’s what i thought initially – must be some sort of new option/function and it doesn’t work as expected. Good luck on solving that stuff ๐Ÿ˜‰ (if not, would be great to have some sort of “on/off” option for it, for those who need that, just my 2 cents)

        Best wishes.

        1. craigo-

          This behaviour was dramatically improved starting with release 3.17.1228.783, and continued improving until the latest release ( – I suggest you try it. And keep watching this space, we are still busy working on the Hyperlink Hotspot feature behind the scenes to make it even better.

    Many many thanks to Rizonesoft for Hyperlink Hotspots’- this was what I missed, excellent work! Now I can use Notepad3 as default text editor! Thank you so much! Regards.

    Where can I download Notepad3_x_3.17.1202.715.exe for replacing Windows Notepad? Thank you. ๐Ÿ™‚

    1. Derick PayneDerick Payne Post author

      I will upload it this evening. Was looking for a better method to replace the Windows Notepad, but will upload the old one for now.

  12. Pavel Trka

    Hi! Is there any changelog or history available ? Notepad3 looks great but I’m kind of unsettled when I don’t know what changed in new version I’m about to install. There is nothing here if I’m not overlooking something and Releases page on gihub seems not up-to-date. Thanks.

      1. Winter Solstice

        Dear Mr. Rizonesoft,
        There is no changes.txt file in either zip file in the portable package. FYI.
        Thank you for your work!

      2. Pavel Trka

        Thanks, I know that’s additional work and but wouldn’t be possible to keep Github releases page up to date ? I’m installing installer version and prefererably through so it’s very cumbersome to download portable version only to look at history ๐Ÿ˜‰

        1. Derick PayneDerick Payne Post author

          Sure thing. I was planning on keeping the GitHub release page up-to-date from now on. ๐Ÿ™‚ Busy working on procedures to help me work more efficiently.

    1. RaiKoHoff

      For your monitor and clear-type font setup it maybe better to switch off Scintillas new Direct Write technology. You can do this within NP3’s settings file, section [Settings2] set SciDirectWriteTech=0.
      You may also change FontQuality ([Settings2] SciFontQuality=0-3, 3 is optimized for LED screens).

      1. Notepa3User

        Thanks @RaiKoHoff
        adding the line “SciDirectWriteTech=0” to my settings file, fixed the issue.
        SciFontQuality didn’t have any effect.

  13. Azmin

    Dear Mr. Derick Payneโ€ฆ ๐Ÿ™‚

    Just want to inform that the latest version you put on download menu was Notepad3 2.17.1016.632 updated on November 21, 2017. But when we downloaded the file was Notepad3_2.17.1023.632.exe
