Learn About Deleting Your Jellyfin Server Safely

Understanding What Jellyfin Is and Why You Might Delete It

Jellyfin is a free, open-source media server software that lets you organize and stream movies, TV shows, music, and photos across multiple devices in your home or over the internet. Think of it as a personal Netflix that you control completely. You install Jellyfin on a computer or server, add your media files to it, and then access those files from phones, tablets, smart TVs, or other computers connected to your network.

People use Jellyfin for different reasons. Some run it to stream their personal movie collection to their living room TV. Others use it to share family photos and videos with relatives. Some tech enthusiasts run it alongside other media services. According to GitHub data, Jellyfin has tens of thousands of active installations worldwide, making it one of the more popular self-hosted media solutions.

You might want to delete your Jellyfin server for several reasons. Maybe you're switching to a different media solution. Perhaps you're shutting down the computer that runs it. You might want to free up storage space, reduce power consumption, or simply no longer need the service. Some people delete Jellyfin when they move homes or upgrade their entire home network setup.

Before deleting anything, it's worth understanding what data exists, where it's stored, and what happens when you remove it. This prevents accidental data loss and ensures a clean removal from your system.

Practical takeaway: Make a list of what media and settings you want to keep before starting any deletion process. Note which devices currently use your Jellyfin server so you understand what will stop working.

Backing Up Your Data Before Deletion

Jellyfin stores two main types of data: your actual media files (videos, music, photos) and your configuration files (settings, user accounts, library information, watch history). Before you delete anything, you should back up the data you want to keep. This is especially important for configuration files, as they contain personalized settings that took time to create.

Your media files are typically stored in separate folders on your computer or external drives. You should copy these files to an external hard drive or cloud storage before deleting Jellyfin. This step is completely separate from uninstalling the software itself. If your media is on a shared network drive or external storage not controlled by Jellyfin, you don't need to worry about losing it when you delete the server—you just need to make sure you're not accidentally moving or deleting the folders Jellyfin points to.

Jellyfin's configuration and database files contain important information like your library setup, user accounts, watched/unwatched status, rating information, and custom artwork. On Windows, these files are typically in C:\Users\[YourUsername]\AppData\Roaming\Jellyfin\. On Linux, they're usually in /home/[username]/.config/jellyfin/ or /var/lib/jellyfin/. On Mac, look in ~/.config/jellyfin/. If you think you might want to restore your Jellyfin setup later, copy this entire folder to an external drive.

Some people create a full system backup before making any major changes. You can use tools like Windows Backup, Macrium Reflect, or Linux tools like Rsync or Clonezilla. This approach protects everything on your system, not just Jellyfin-related data. A full backup takes longer and requires more storage space, but it's the safest option if you're uncertain about what you might need later.

Practical takeaway: Copy both your media folders and your Jellyfin configuration folder to an external hard drive. Label the backup with the date. Keep it in a safe location for at least 30 days after deletion in case you need something.

Removing Jellyfin from Windows Systems

On Windows, removing Jellyfin involves several steps. The basic approach is straightforward, but there are details worth understanding to ensure complete removal. Start by stopping any running Jellyfin processes and then uninstalling the application through Windows settings.

First, close any Jellyfin applications that are currently running on your system, including the Jellyfin server application itself and any web browser windows showing the Jellyfin interface. Open the Windows Services app by typing "services.msc" into the Start menu search. Look for "Jellyfin Server" in the list. Right-click on it and select "Stop" to halt any background processes. Then right-click again and select "Delete" to remove it from your Windows services list. This step prevents Jellyfin from trying to start automatically when your computer boots up.

Next, go to Settings > Apps > Apps & Features. Search for "Jellyfin" in the list. Click on it and select "Uninstall." Windows will walk you through the uninstallation process. After the uninstaller finishes, Windows may ask you to restart your computer. Go ahead and restart to complete the removal.

After restarting, you should manually check and remove leftover files. Navigate to C:\Users\[YourUsername]\AppData\Roaming\ and look for a "Jellyfin" folder. Delete this folder entirely. Also check C:\Program Files\ and C:\Program Files (x86)\ to make sure no Jellyfin folders remain. Sometimes installers leave behind residual files in unexpected locations. You can also use the Windows search function to search for "jellyfin" across your entire C: drive to catch any remaining files.

If you installed Jellyfin using a specific installer or package manager, follow that service's uninstallation instructions. For example, if you used Chocolatey, run choco uninstall jellyfin in PowerShell. The process may differ slightly depending on how you originally installed it.

Practical takeaway: Use Windows Services to stop the background process first, then uninstall through Settings, then manually delete remaining folders. This three-step approach prevents most problems.

Removing Jellyfin from Linux Systems

Linux systems have different distributions, and Jellyfin removal varies slightly depending on which one you use. However, the basic concept is the same across all Linux distributions: stop the service, uninstall the package, and remove configuration files.

For Ubuntu and Debian-based systems, open a terminal and stop the Jellyfin service first by typing sudo systemctl stop jellyfin. Then disable it from automatically starting on boot with sudo systemctl disable jellyfin. Next, remove the package with sudo apt remove jellyfin or sudo apt-get remove jellyfin. This removes the application but leaves configuration files in place in case you change your mind. If you want to remove everything including configuration files, use sudo apt purge jellyfin instead. This command removes the package and all associated configuration data in one step.

For Fedora or Red Hat-based systems, use sudo dnf remove jellyfin or sudo yum remove jellyfin depending on which package manager your system uses. Again, this removes the software but keeps configuration files. Use sudo dnf autoremove afterward to clean up any dependencies that are no longer needed.

If you installed Jellyfin from source code rather than through your distribution's package manager, you'll need to manually delete the installation directory. This is typically in /opt/jellyfin/ or /usr/local/jellyfin/. Stop the service first, then remove the directory with sudo rm -rf /opt/jellyfin/. Be extremely careful with the rm -rf command, as it permanently deletes files without recovery options. Double-check the path before executing it.

After removing the package, manually clean up remaining files. Remove the Jellyfin configuration directory with sudo rm -rf /etc/jellyfin/, the data directory with sudo rm -rf /var/lib/jellyfin/, and the user home directory with sudo rm -rf /home/jellyfin/
