JDownloader 2 is a free, open-source download management tool with a huge community of developers that makes downloading as easy and fast as it should be. Users can start, stop or pause downloads, set bandwidth limitations, auto-extract archives and much more. It’s an easy-to-extend framework that can save hours of your valuable time every day. In this step by step guide I will show you how to install JDownloader 2 on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest JDownloader 2 v24.09.1 release.

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it jdownloader2. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create two new folders inside the jdownloader2 folder that you have previously created at STEP 3 and name them config and output. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.
