STEAMID I/O lookup and convert your steamID, steamID3, steamID64, customURL and community id

STEAMID I/O: convert steamIDs, steamID64s, steamID3s, customURLs and find Steam Community profiles.

steamIDs

A steamID is a unique identifier used to identify a Steam account. A steamID can be converted to the newer steamID3 and to a steamID64, sometimes referred to as community ID or friendID. With this steamID64, a user's Steam community page can be found. A customURL is an optional, more personalised identifier to look up a user's Steam Community page with.
