Are you sure you're not confusing JDownloader with something else? JD is free and open source, there is no premium JD.

It happily integrates with various debrid services though. Like Realdebrid in your case.

 

There is no premium JD2, it's just a freeware downloader, you only can go premium with your file sharing account and then add it to JD2 in its settings.
Since JD2 has multiple options to set several connections for each file or download multipe files at once, you can reach the maximum speed
of what your internet connection provides.

In my case thats around 62MB/s while downloading through the browser is at 20-30MB/s.

But one of the best features of JD2 for me is:
You can put everything to download in the list, let it download over night, JD2 then extracts the files (if a pw is required, you can simply add it),
deletes the archives and shuts down your PC (if you set JD to do that).

 

Thank you guys. It's the first time I'm using JD2. What I saw was premium ads for Rapidgator and the like. I can't understand why I've missed this tool for so long.

 

As the others already mentioned, you can integrate a hoster's premium account into JD2 so it even enters your password automatically.

 

Katfile is the best because its the only hoster you can edit to give you full speed downloads. Also why are you not using adblock in 2024?

 

Try uBlock Origin instead of adblock for a few days see what you think.

 

I denounce thee that shitteth upon the Katfile.
