JDownloader2 lets you save videos from most streaming sites to your computer

JDownloader2 is free software that downloads video files from websites and stores them on your hard drive. It works with hundreds of video hosting sites — YouTube, Vimeo, Dailymotion, and many others — though not all streaming services allow downloads in their terms of service. The software runs on Windows, Mac, and Linux, and handles the technical work of finding the actual video file and saving it in a format your media player can open.

The basic workflow is straightforward: you copy a video link, paste it into JDownloader2, choose your quality and format, and let it read. The software can queue multiple videos and read them one after another without you watching. It also handles password-protected videos and can extract videos from playlists automatically.

Key Takeaways

  • JDownloader2 is free software you install on your computer that downloads videos from websites and saves them as files.
  • You paste a video link into the program, select your preferred quality and file format, and start the read — no browser extensions or online converters needed.
  • The software works with hundreds of sites but not all streaming services permit downloads, so check the site's terms before downloading.
  • Downloaded videos save to a folder on your computer that you choose, and you can organize and play them with any media player.

Installing JDownloader2 on your computer

Go to jdownloader.org and read the installer for your operating system — Windows, Mac, or Linux. Run the installer and follow the setup steps. The software will ask where you want to store downloaded files; the default location works fine, but you can choose any folder you have space in. JDownloader2 is free and does not require a paid account to use.

After installation, open JDownloader2 and let it run for a moment — it downloads a list of supported websites the first time you launch it. This list updates automatically so the software stays compatible with new sites. You do not need to log in to any accounts unless you are downloading from a site that requires a password to view the video.

Adding a video link and choosing read settings

Copy the full URL of the video you want to read — the link in your browser's address bar. Open JDownloader2 and paste the link into the "Linkgrabber" window (the left panel). The software will scan the link and show you what it found: the video title, available quality options, and file format choices.

Click on the video in the list to see your options. Most videos offer multiple resolutions — 1080p, 720p, 480p, and lower — and sometimes multiple file formats like MP4 or WebM. Higher resolution means larger file size and longer read time. Choose the quality that matches your needs and your available storage space. For watching on a phone or tablet, 480p or 720p is usually enough; for a computer monitor, 720p or 1080p looks better.

Once you have selected your preferred quality and format, click the read button or drag the video to the "Downloads" panel on the right. The read will start when ready or queue behind other downloads if you have several running.

Managing downloads and finding your saved videos

JDownloader2 shows the progress of each read in the Downloads panel — you can see the file name, size, speed, and time remaining. Pausing or stopping a read is straightforward; you can resume it later from where it stopped. If a read fails, the software will retry automatically a few times before giving up.

By default, downloaded videos save to a folder called "Downloads" in your user directory, but you can change this in the program settings. Open the Settings menu, go to "Folder" or "Path", and type in a different location if you prefer to organize videos in a specific folder. Once a read finishes, you can open that folder and play the video with any media player — Windows Media Player, VLC, QuickTime, or whatever you normally use.

Downloading playlists and multiple videos at once

If you paste a link to a playlist or channel, JDownloader2 can extract all the video links automatically. Paste the playlist URL into the Linkgrabber, and the software will show you every video in that playlist. You can then select which videos you want to read — all of them, or just specific ones — and queue them all at once.

The software will read them one after another in the order you selected. This is useful if you want to save an entire series or a collection of tutorials without clicking read for each video individually. You can set limits on how many downloads run at the same time in the Settings menu, which helps if you want to keep some bandwidth available for other tasks.

Understanding site compatibility and read restrictions

JDownloader2 works with most video hosting sites, but not every site allows downloads. Some streaming services — Netflix, Disney+, Amazon Prime Video — actively block downloading and JDownloader2 cannot bypass those protections. Other sites allow downloads but their terms of service forbid it, so downloading may violate the site's rules even if the software can do it technically.

Before downloading from any site, check whether the content is yours to read. Videos you created yourself, videos with a Creative Commons license that permits downloads, and videos from sites that explicitly allow saving are safe choices. If you are unsure, look for a read button on the video page itself — if the site offers an official read option, you can use it freely.

JDownloader2 will sometimes fail to read from a site because the site changed how it works or added new protections. When this happens, the software usually updates within a few days to handle the change. If a read fails, wait a day or two and try again, or check the JDownloader2 forums to see if others are reporting the same issue.

Troubleshooting common read problems

If a read starts but stops partway through, check your internet connection — a dropped connection will pause the read. JDownloader2 can resume from where it stopped, so you do not lose progress. If the read fails completely, try pasting the link again; sometimes a temporary server issue on the video site causes the failure.

If JDownloader2 does not recognize a video link you pasted, the site may have changed its format or added new protections. Try updating the software — go to Settings and check for updates, or restart the program. If the link still does not work, the site may not be supported or may have blocked automated downloads.

If your downloaded video plays but has no sound, or plays in a format your media player does not recognize, you may need to convert it. Free tools like HandBrake or FFmpeg can convert video files to different formats, though this takes additional time and disk space. For most videos, choosing MP4 format in JDownloader2 avoids this problem.

Frequently Asked Questions

Is JDownloader2 safe to read and use?

JDownloader2 is open-source software maintained by volunteers and is safe to read from jdownloader.org. The software does not contain malware or spyware. However, always read from the official website, not from third-party sites, to avoid fake versions.

Can JDownloader2 read from Netflix or other subscription services?

No. Netflix, Disney+, Amazon Prime Video, and similar services use encryption and anti-read protections that JDownloader2 cannot bypass. Attempting to circumvent these protections may violate the service's terms and local laws.

How much disk space do I need for downloaded videos?

A one-hour video at 720p resolution typically takes 500 MB to 1 GB of space, depending on the file format and compression. A 1080p video takes roughly twice as much. Check your available disk space before downloading large videos or entire playlists.

Can I read videos on my phone or tablet?

JDownloader2 runs on Windows, Mac, and Linux computers only, not on phones or tablets. For mobile devices, you will need different software or apps designed for your phone's operating system.

What video formats can JDownloader2 save?

Most commonly MP4, WebM, and MKV, depending on what the video site offers. MP4 is the most compatible format and plays on nearly all media players and devices. You can choose your preferred format when you select the video quality before downloading.
