Frequently Asked Questions
What Steam ID formats does this convert?
It converts between SteamID64 (the 17-digit 7656119... number), the legacy STEAM_X:Y:Z form, the SteamID3 [U:1:W] form, the bare 32-bit account ID, and the steamcommunity.com/profiles/ URL. Paste any one and you get the rest.
How does SteamID64 map to the account ID?
A SteamID64 for an individual account is a fixed base of 76561197960265728 plus the 32-bit account ID. To go back, subtract the base. In STEAM_X:Y:Z the account ID is Z * 2 + Y, where Y is the lowest bit.
Can it resolve a vanity URL like steamcommunity.com/id/name?
No. Vanity (custom) URLs are not derived from the SteamID by math - they require a Steam Web API lookup. Open the profile, switch to the numeric /profiles/ URL, and paste that instead.
Is my Steam ID sent anywhere?
No. The conversion is pure arithmetic that runs entirely in your browser with BigInt. There is no network request and nothing is stored.
Why does STEAM_0 sometimes show as STEAM_1?
The first digit is the Steam universe. Public accounts are universe 1, but older tools and CS:GO historically printed it as 0. They refer to the same account; this tool accepts both on input and outputs STEAM_1.
