What Is a Torrent Info-Hash?
The info-hash is the SHA-1 hash of a torrent's info dictionary — its unique fingerprint on the BitTorrent network. Magnet links use this hash to find peers without needing a tracker or .torrent file. Convert yours now: Torrent to Magnet →
Why Switch to Magnet Links?
- No file to store — a magnet link is a short text string you can copy anywhere
- Works without trackers — DHT finds peers even if all trackers are offline
- Never expires — permanent link that always works
- Smaller — under 200 bytes vs kilobytes for a .torrent file
- Easy to share — paste into any modern torrent client
What a Magnet Link Doesn't Preserve
Converting to a magnet link isn't purely a gain — the original .torrent file's exact piece-size configuration and any embedded comment or creator metadata aren't part of the magnet URI standard, so a client rebuilding the torrent from the magnet link alone may negotiate different piece sizes with peers than the original file specified. This rarely matters for typical downloads, but for exact archival or verification purposes where the original piece hashes matter, keeping the source .torrent file alongside the magnet link is the safer choice.
Why DHT Isn't Always a Complete Substitute for Trackers
DHT lets peers find each other without a central tracker, but it depends on your torrent client being able to reach the DHT network at all — many corporate and school networks block the UDP ports DHT relies on, and some ISPs throttle or block DHT traffic specifically as an anti-piracy measure. In those situations, a magnet link with no working trackers listed can fail to find any peers at all, even though the same content would download fine over an unrestricted connection.
Batch Conversion
Drop multiple .torrent files at once and get a magnet link for each. Perfect for converting an entire torrent library to magnet links in one go.

Your .torrent files are parsed in your browser using JavaScript. The SHA-1 info-hash is computed locally using the Web Crypto API. Nothing is uploaded to our servers.
