Plex is one of the most popular media server platforms in the world, offering beautiful interfaces, smart metadata, streaming apps, and remote access. Running Plex on a Raspberry Pi gives you a low-cost, always-on media server for your home. This guide explains how to install Plex, what you can do with it, and whether a Raspberry Pi can handle transcoding.
Why Use Plex on a Raspberry Pi?
A Raspberry Pi makes an excellent lightweight Plex server because it is:
- Affordable
- Low-power (uses far less energy than a PC or NAS)
- Quiet (fanless on most models)
- Capable for direct streaming
What You Need
- Raspberry Pi 3, 4, or 5 (Pi 4 or 5 recommended)
- Raspberry Pi OS Lite or Desktop
- External storage for media files
- Network connection (Ethernet recommended)
How to Install Plex Media Server on Raspberry Pi
Step 1: Update Your System

Can a Raspberry Pi Handle Plex Transcoding?
This depends heavily on the Raspberry Pi model and the video format.
Raspberry Pi 3
- Very limited CPU power
- Transcoding: No
- Best for direct play and direct stream only
Raspberry Pi 4
- Good performance for lightweight media serving
- Software transcoding: Very limited (usually 480p → 720p)
- Hardware transcoding: Not supported
- Direct play works flawlessly
Raspberry Pi 5
- Much faster than Pi 4
- Still not good for heavy transcoding
- Most content should use direct play
Conclusion
A Raspberry Pi running Plex is perfect as a low-cost, silent media server that handles direct streaming extremely well. However, transcoding performance is limited—even on the Raspberry Pi 5. For best results, ensure your media is in a compatible format so clients can direct play without conversion.
