How to Use the SteamID Converter

  1. Paste any Steam identifier: a 17-digit SteamID64, a legacy STEAM_0:Y:Z or STEAM_1:Y:Z string, a SteamID3 like [U:1:88298237], a bare account ID, or a steamcommunity.com/profiles/ URL.
  2. Read every other format instantly - the conversion is pure BigInt arithmetic in your browser.
  3. Copy the format you need with the copy button next to each row.

Where Each Format Shows Up

  • SteamID64 (7656119...) - the Steam Web API, third-party stat sites, trade and inventory tools, and /profiles/ URLs.
  • STEAM_X:Y:Z - legacy GoldSrc and Source engine output: CS 1.6/CS:GO status listings, server bans, SourceMod admin configs.
  • SteamID3 [U:1:W] - newer Source engine games and CS2's status command, plus server logs.
  • Account ID - the raw 32-bit number used in game files, friend codes math, and database keys.

Notes and Edge Cases

The math is fixed: SteamID64 = 76561197960265728 + account ID for individual accounts, and in STEAM_X:Y:Z the account ID is Z * 2 + Y. The universe digit prints as STEAM_1 here; older tools printed STEAM_0 for the same account and both are accepted on input. Custom /id/name vanity URLs are the one thing math cannot convert - they are a name-to-ID mapping that lives on Valve's side. When you paste one, the tool offers a lookup that asks our server to resolve the name via the Steam Web API; only the name itself is sent, nothing is stored. If you prefer to stay fully offline, open the profile in Steam and copy the numeric /profiles/ URL instead.

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?

Yes. Vanity (custom) URLs are not derived from the SteamID by math, so the tool offers a one-click lookup that resolves the name through the Steam Web API on our server - only the name is sent, nothing is stored. Prefer to stay offline? Paste the numeric /profiles/ URL 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.
