HOW TO DOWNLOAD TORRENTS WITHOUT ANY SOFTWARE:

You can download torrents without using any software by using a free online torrent client. The best one is called Seedr. It supports files up to 2 GB. Other free options include Zbigz and BitPort, but they only support files up to 1 GB. Seedr & BitPort require you to register, but it is free. Another free online torrent client, FileStream, requires registration and supports files up to 200 MB.

Where do you get torrents? There are plenty of sites. If you like movies, the site I prefer is YIFY Torrents. The Pirate Bay is also very popular.

Download your torrent or copy its magnet link [the online address of the torrent] and upload/paste it into the online torrent client.



The client will piece the files together and give you a download link. That's all there is to it!
