Steam ID converter
Convert public individual SteamID64, SteamID2 and SteamID3 exactly.
Convert a public individual desktop Steam ID between SteamID64, STEAM_1:Y:Z and [U:1:ID]. Conversion uses exact integer arithmetic in your browser and makes no source request.
Legacy STEAM_0 input is normalized to the public universe. Group, server, non-public universe and invalid identifiers are rejected rather than being presented as individual accounts. A successful conversion does not confirm that an account exists.
