MangaDownloader is a free portable manga downloader that can grab all available online mangas from different sites. We are not a big fan of mangas, here at AddictiveTips, but can guarantee that all fans will find this tool quite neat and useful.
What makes it different and unique is the easy-to-use graphical interface. On the left sidebar you will find hundreds of available mangas that cannot be found anywhere else. Upon selecting a manga, you will find the information, summary, and cover image on the main window. Select the chapter that you want to read and hit Begin Download to save it for offline viewing.
By default all mangas are saved inside Document folder but the location can be changed from Settings. The mangas are downloaded in zip archive format and can be imported in ComicRack, a popular comic book reader.
The Java application worked seamlessly on our Windows 7 32-bit test machine.
