About Torrent File Viewer

A torrent file viewer opens a .torrent file and shows what is inside it without starting a download: the name, the files and their sizes, the trackers, the piece layout and the info hash that identifies the torrent on the network. This one parses the bencoded file locally in your browser, computes the info hash from the exact bytes of the info dictionary, and builds a magnet link you can copy. Nothing is uploaded, and nothing is downloaded either.

Key Features

Reads single-file and multi-file torrents and lists every path with its size
Computes the v1 SHA-1 info hash from the raw info dictionary bytes, not a re-encoded copy
Detects BitTorrent v2 and hybrid torrents and shows the SHA-256 info hash too
Shows trackers grouped by tier from announce-list, plus web seeds from url-list
Builds a magnet link with the hash, display name and every tracker
Filters large file lists instantly and flags padding files and the private flag
Rejects malformed bencode and trailing garbage with the byte offset of the problem

Use Cases

Check what a .torrent contains before adding it to a client, for example whether a Linux ISO release ships the files you expect
Turn a .torrent into a magnet link to paste into a chat or a ticket
Compare the info hash of a release you mirrored on an AWS S3 bucket against the one the maintainer published
Audit trackers and the private flag before sharing an internal build artifact torrent
Debug a torrent your own tooling created by checking piece length, piece count and file order
Inspect a hybrid v1 and v2 torrent to confirm both hashes were generated

What is an info hash and how is it calculated from a torrent file?

The info hash is the SHA-1 digest (SHA-256 for BitTorrent v2) of the bencoded info dictionary inside the .torrent file. It is the identity of the torrent: two files with different trackers or comments but the same info dictionary have the same hash and join the same swarm. The detail that trips up homemade tools is that the hash covers the original bytes, not a decoded and re-encoded copy. If a parser sorts keys, normalizes integers or drops unknown fields before hashing, the result no longer matches what clients compute. This viewer slices the info dictionary straight out of your file and hashes those bytes, so the value it shows should match what any client reports for the same file. A magnet link is just that hash plus an optional display name and tracker list in URL form.

Does this tool upload my torrent file anywhere?

No. The file is read with the browser File API and parsed in your tab. The info hash uses the Web Crypto API. Nothing is sent to a server, and the viewer never contacts a tracker or joins a swarm, so opening a torrent here leaves no trace on the network.
