LosslessCut is available on Linux as a standalone AppImage and through app stores. For most x86_64 desktop PCs, the official GitHub AppImage is the simplest route to the newest build; it does not require AppImageLauncher.
Versions can differ by distribution channel. On October 21, 2026, GitHub marked v3.70.1 as the latest release, while Snapcraft and Flathub showed v3.69.0. Check the live listings before downloading because packages update on different schedules.
Run uname -m in Terminal. Use the x86_64 AppImage only when the result is x86_64. For ARM devices, choose the matching arm64 or armv7l archive from the official releases; the project’s download notes say its ARM tar builds do not include FFmpeg. the Flathub listing includes x86_64 and aarch64 builds and marks the package as community provided.
On the LosslessCut Releases page, download LosslessCut-linux-x86_64.AppImage. Or run these commands to save it in ~/Applications:
mkdir -p "$HOME/Applications"
curl -L "https://github.com/mifi/lossless-cut/releases/latest/download/LosslessCut-linux-x86_64.AppImage" -o "$HOME/Applications/LosslessCut-linux-x86_64.AppImage"If you downloaded it in a browser, move the file from Downloads into that folder or adjust the following commands to match its location.
Right-click the file, open Properties, and look for an execution permission on the Permissions tab. On GNOME, enable Allow executing file as program. The wording varies by desktop; if there is no checkbox, use:
chmod +x "$HOME/Applications/LosslessCut-linux-x86_64.AppImage"This marks the downloaded file as runnable. Only run AppImages from sources you trust; the AppImage instructions explain the executable permission requirement.
Double-click the AppImage and choose the option to run it if your desktop asks. You can also launch it from Terminal:
"$HOME/Applications/LosslessCut-linux-x86_64.AppImage"Since v3.70.0, the project’s Linux AppImage no longer requires libfuse2, so older guides that make this library a required step are outdated for current releases. For other launch errors, check the project’s Linux troubleshooting notes.
To update, replace the AppImage with a newly downloaded release and repeat chmod +x if needed. To remove this installation, quit LosslessCut and delete the AppImage file. This does not remove a separate Snap, Flatpak, or AUR installation.
LosslessCut is published by the developer in the Snapcraft listing. If Snap support is enabled, run:
sudo snap install losslesscutIf snapd is missing, follow the Snap setup instructions for your distribution first. Ubuntu 18.04 and later commonly include Snap support; other defaults vary. Snap packages update through the Snap service, though the store version may lag behind GitHub.
The Flathub listing identifies this as a community-maintained build, which the developer does not verify or support. If Flatpak is installed but Flathub is not configured, add the remote and install LosslessCut:
flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install --user flathub no.mifi.losslesscutStart it from your app menu or run:
flatpak run no.mifi.losslesscutInstall Flatpak first using your distribution’s setup instructions if the command is unavailable. You can also install the app from a software center after adding Flathub.
Arch users can use the AppImage or the community AUR package losslesscut-bin. With an AUR helper such as yay, install it with yay -S losslesscut-bin. AUR recipes are maintained by community contributors, not the LosslessCut developer; inspect the current PKGBUILD and source details before building.
chmod +x step and confirm the file path.uname -m; the x86_64 AppImage will not run on ARM.For a typical x86_64 Linux PC, downloading, enabling execution, and launching the AppImage is all that is required. Choose Snap for a store-managed install or Flathub if you accept its community-package status.
Capture Linux desktop audio in Audacity by routing its recording stream to your output device’s monitor source. Follow PulseAudio and PipeWire steps, export tips, and fixes for silent tracks.
Install Dropbox on Linux from the official package, sign in, sync a local folder, manage selective sync, and check status from the command line.
Install Inkscape from your Linux distribution’s repositories, the Ubuntu stable PPA, Snap, or Flathub, with current commands and notes for choosing a package source.
Use FSlint to scan selected Linux folders, review duplicate groups, and safely delete redundant files or learn when hard-link merging is appropriate.
Install SABnzbd on Ubuntu or Debian, or run it in Docker on another Linux host. Then open the web interface and configure your provider and download folders.
Install the Paper GTK theme from supported Linux repositories, enable it for GTK apps in GNOME Tweaks, and see what the legacy theme can and cannot change.
The old OpenMediaVault Plex plugin is archived. Set up Plex on OMV 8 with OMV-Extras, the Compose plugin, persistent storage, and Plex’s official container.
Clean and speed up Ubuntu with safe APT cleanup, storage checks, and startup controls that help free space and troubleshoot a sluggish desktop.
Install Hiri on Linux with its Snap package or official tarball, add a desktop launcher, and check supported accounts plus a warning about Hiri’s old Snap release.
Use Fastfetch and built-in Linux commands to check your distro, kernel, CPU, memory, graphics, storage, and connected devices, then save a clear report.
