AppImages are alternatives to the classic Linux apps. While uncommon in usage, they're practical insofar as they run on several Linux distros all the same. And you might want to treat them like you treat your usual applications. Read on to find out how to do so.

The Scenario:
You have an .AppImage file and would like to treat it like an installed Linux app.

The solution:
Create a custom .desktop file

For this article, I'll use the following constraints:

  • Register the Electron.js app Marktext on an Ubuntu 20.04 distro
  • Use this icon from

Let's do it.

NOTE: You might have to use sudo commands to access files in the /bin and /use directories
  1. Download the .AppImage file and an icon you would like to register it with
  2. Move the .AppImage file to the path /bin,
    e.g. sudo mv ~/Downloads/Marktext.AppImage /bin/
  3. Make it executable with sudo chmod +x /bin/Marktext.AppImage
  4. Save the icon under /use/share/icons/custom/markdown.png
    e.g. sudo mkdir --parents /use/share/icons/custom && sudo mv ~/Downloads/markdown.png /use/share/icons/custom/
  5. Create a .desktop file under ~/.local/share/applications/marktext.desktop
  6. Paste the following content into it:
[Desktop Entry]
Name=Mark Text
Comment=Next generation markdown editor
Exec=/bin/marktext-x86_64.AppImage        # replace with your .AppImage
Icon=/usr/share/icons/custom/markdown.png # replace with your icon
Keywords=marktext;markdown;               # add searchable keywords

That should do it. Try pressing the Super key now and search for the app.

Hitting enter should then startup your application.
