How can I install the Notepad++ Hex-Editor plugin for Windows? The plugin seems to have been difficult to install in the past, and Notepad++ does not currently have integrated plugin management in the GUI.

(I no longer use the Notepad++ Hex-Editor, although I am using Notepad++ itself more and more. The Hex-Editor does not include undo support, which is a deal-breaker for me. Instead, I use HxD, which is both powerful and beginner-friendly.)

  • I am using Hex-Editor plugin, and Notepad++ always disable it when upgrading. It's because, in some cases, it display wrong values. You have been warned – Jimbot Dec 5 '18 at 14:02
  • Thanks. HxD looks like an excellent replacement until Hex-Editor is repaired. – Laurie Stearn Jan 22 at 5:44

As of 13 Nov 2018 Plugins Admin is included in the notepad++ installer by default. Select the tab Plugins and click on Plugins Admin... then scroll down or search for HEX-Editor.

By the request of community, a built-in Plugins Admin is available in Notepad++ v.7.6.

  • The Plugin Manager was removed from Notepad++ 7.5 because of sponsored advertising (see the second screenshot in the answer), although it will still be there if you upgraded from an older version of Notepad++.

    You may notice that Plugin Manager plugin has been removed from the official distribution. The reason is Plugin Manager contains the advertising in its dialog. I hate Ads in applications, and I ensure you that there was no, and there will never be Ads in Notepad++. A built-in Plugin Manager is in progress, and I will do my best to ship it with Notepad++ ASAP.

  • This is currently being worked on (the maintainer of the plugin and the plugin list will be integrating free hosting into the plugin manager to get rid of the advertising)

  • In the meantime you can install it manually (download here).

It is advised to still use the Plugin Manager (as this manages updating of your installed plugins)

  1. Click Menu > Plugins > Plugin Manager > Show Plugin Manager

    enter image description here

  2. This now shows a list of available plugins, including Hex-Editor:

  3. Select the Hex-Editor plugin and then click Install.

    I do not see that menu option. I have a "Plugins" menu, but no "Plugin Manager" sub-menu. I'm using Notepad++ v7.5.6 32 bit. Could the plugin manager itself be a plugin? – Josiah Yoder May 23 '18 at 15:28
  • Indeed it is now, I didn't realise. See updated answer. – DavidPostill May 23 '18 at 17:39

    Perhaps things have changed since May, but HEX-editor is no longer in the list of available plugins in the plugin manager. (edit: this might be because I'm running 64-bit npp) – csauve Aug 30 '18 at 18:34

    @csauve Could be. I'm running 32bit notepad++ – DavidPostill Aug 30 '18 at 19:24

    @csauve I found a 64-bit version on GitHub: NPP HexEdit. Just download the HexEditor_0.9.5.19_x64.zip version. – Mr. Polywhirl Sep 18 '18 at 23:56

First, install Notepad++.

Next, download the latest HexEditor .ddl plugin. I downloaded HexEditor_0_9_5_UNI_dll.zip. (For some reason, the most obvious green download button takes you to an HTMLTag_plugin, which looks like a dead-end to me.)

Finally, open the zip file, select the HexEditor.dll file and place it in the folder

C:\Program Files (x86)\Notepad++\plugins\HexEditor

if you installed the 32-bit version of Notepad++ and

C:\Program Files\Notepad++\plugins\HexEditor

if you installed the 64-bit version. (For older versions of Notepad++, omit the HexEditor folder)

To test if your install was successful, restart Notepad++, and you should see a menu option Plugins -> Hex-Editor -> View in Hex. This will toggle whether you are viewing the file in hex.

The Notepad++ hex editor does not have undo support, so I no longer use it. (I am still using Notepad++ itself.) Instead, I use HxD, which is both powerful and beginner-friendly.

Thanks to Bálint and momolang momo for pointing out the need for the HexEditor folder in newer versions.

  • HxD was a great tip. Easy to install and use. – Casper Nov 30 '18 at 9:33
  • The downloadable binary for the plugin seems to only work with 32bit - my 64bit NPP refused to load the plugin saying that it's incompatible because it's 32bit. – ChrisWue Feb 7 at 1:54
  • momolang suggests that it must also go within a folder called "HexEditor". I have not confirmed this. – Josiah Yoder yesterday

    @JosiahYoder Just confirmed it for you. It wouldn't load without placing it inside a folder with the same name. – Bálint yesterday
  • @Bálint Thank you. I've edited the question accordingly. – Josiah Yoder 11 hours ago

If the solutions above do not work, try the following:

  1. Open the following folder (insert your username):

    C:\Users\<User name>\AppData\Local\Notepad++\plugins
  2. Create a subfolder HexEditor

  3. Copy the HexEditor.dll file into this subfolder. Windows will probably request permission to do this.

  4. Restart Notepad++

This worked for me on Notepad++ 7.6 32bit


Adding HexEditor.dll to AppData does not work for me. But by create a C:\Program Files\Notepad++\plugins\HexEditor and put the dll into it, then it work fine for me.

I am using Npp v7.6.6 (64-bit) on window 10
