APPIMAGE File

What are APPIMAGE files and how to open them

Are you having problems opening an APPIMAGE file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your APPIMAGE files.

What is an APPIMAGE file?

An .APPIMAGE file is an AppImage Package file.

AppImage Package files store Linux applications together with all their dependencies in a single self-contained executable. The format makes applications portable across many Linux distributions without needing installation or root permissions. An AppImage file wraps its payload in a compressed filesystem (usually SquashFS) and includes a small ELF runtime at the front that mounts that payload and launches a defined entry point.

The creator of these files is the AppImage project (through its reference implementation called AppImageKit). Developers bundle applications by first preparing an AppDir folder containing the executable entry point (AppRun), metadata such as a .desktop file, icons, and all necessary libraries and resources. Then a tool called appimagetool builds the final AppImage by compressing the AppDir into a SquashFS filesystem, prepending the ELF runtime, and producing a single file which can be run.

When run, an AppImage file mounts its internal filesystem (often using FUSE) so that the operating system sees a directory tree ($APPDIR) containing everything the application needs. The entry point (AppRun) inside that tree is executed. Configuration files for the app are written into the user's home directories unless special "portable mode" directories exist alongside the AppImage.

The format can be identified by its ELF magic number at the very beginning of the file (".ELF" signature at offset 0) combined with embedded strings such as "APPIMAGEKIT" and many of the standard ELF section names (TEXT, DYNAMIC, GOT, PLT, etc.).

How to open APPIMAGE files

Important: Different programs may use files with the APPIMAGE file extension for different purposes, so unless you are sure which format your APPIMAGE file is, you may need to try a few different programs.
