JDownloader is a download manager, written in Java, which allows the automatic downloading of files and split files from one-click hosting sites such as RapidShare. JDownloader supports the use of premium accounts.[1] Certain parts of JDownloader are open source.

JDownloader is better known in Spain and other Spanish-speaking countries. As of December 2009 the program's website is in the top 1000 sites by traffic from Spain.[2] The German online magazine, Chip.de designated it "newcomer of the year" for 2009 after it ranked among top 50 downloads with over half a million downloads for the year.

JDownloader supports the RapidShare "waiting time" and CAPTCHA recognition, enabling batch downloads without user input.[6] Premium users of one-click-host sites have the added advantage of using multiple connections per downloaded file, which accelerates the download in most cases. It also supports Metalink, a format for listing multiple mirrors. Software updates and minor patches are released frequently, and by default JDownloader will update itself upon initialization.
