An AppImage is a downloadable file for Linux that contains an application and everything the application needs to run (e.g., libraries, icons, fonts, translations, etc.) that cannot be reasonably expected to be part of each target system.
Make it executable and double-click it.
Using the optional appimaged daemon, you can easily integrate AppImages with the system. The daemon puts AppImages into the menus, registers MIME types, icons, all on the fly. You can download it from this repository. But it is entirely optional.
See the "repository" of upstream-generated AppImages.
An important point about the AppImage format is that you can store AppImage files wherever you want. This includes your home directory, your downloads directory, a dedicated applications directory, a USB thumb drive, a CD-ROM or DVD, or even a network file share. No matter where you keep your AppImages, you are still able to run them. This is very similar to how applications work on macOS. Unlike with traditional Linux packages, you do not need to install AppImages or put them into some special location in order for them to work.
If you don't want to leave them in
$HOME/Applications is a good choice. Many third-party tools (especially the ones managing desktop integration) use this location, too. Other options involve
$HOME/bin, which are useful mainly for CLI tools.
On CentOS/RHEL and Fedora: When you login, the script
$HOME/.bash_profile is executed and this script adds
$HOME/.local/bin:$HOME/bin to your path.
On Ubuntu: When you login, the script
$HOME/.profile is executed and this script adds
"$HOME/bin:$HOME/.local/bin" to your path.
Besides, every other location works, e.g., a USB thumbdrive, a network location, or a CD-ROM, but then the AppImages won't be on your path, which means that you cannot simply type their name into a terminal but have to use the full path.
If there is no AppImage of your favorite application available, please request it from the author(s) of the application, e.g., as a feature request in the issue tracker of the application.
For example, if you would like to see an AppImage of Mozilla Firefox, then please leave a comment at https://bugzilla.mozilla.org/show_bug.cgi?id=1249971. The more people request an AppImage from the upstream authors, the more likely is that an AppImage will be provided.
