qBittorrent

qBittorrent is a well established open-source BitTorrent client. qBittorrent features a light footprint, whilst providing all the features you may need. It uses the high-tech libtorrent-rasterbar library, which means greater download and upload speed, as well as excellent support of the latest features in the BitTorrent protocol.

Why use qBittorrent instead of another client?

There are several BitTorrent clients that are functional, but this is why we like qBittorrent:

• It has no ads
• It is free and open-source, so you can review the code and see what qBittorrent is doing. This means you don't have to worry about qBittorrent embedding malware, trackers, or other dangerous code
• A built-in search engine that allows users to search for torrents directly from the client
• Support for a wide variety of file formats and protocols including magnet links, DHT, PEX, and LSD
• A feature-rich and customizable interface that includes a built-in torrent creation tool
• Support for sequential downloading, which allows users to stream a video file as it is downloading
• An integrated RSS feed reader and downloader
• Remote control via a web user interface.
• It features an anonymous mode for better privacy

Which operating systems are supported by qBittorrent?

qBittorrent is compatible with the vast majority of operating systems such as GNU/Linux, BSD, all the versions of macOS and Windows.

Is it legal to use qBittorrent?

qBittorrent is a peer-to-peer (P2P) file sharing software. Although the software is perfectly legal, it may be illegal to download or share some content, depending on local law.

Is qBittorrent's Anonymous mode private enough?

Anonymous mode doesn't provide strong privacy guarantees on its own. If you are concerned about copyright troubles, consider using a VPN instead. When the Anonymous mode is enabled, qBittorrent takes certain measures to try to mask your identity, preventing your BitTorrent traffic from being associated with you.
