Steam ID Converter

Convert any numeric Steam ID between SteamID64, SteamID3 and SteamID2 — and jump straight to the profile. Fully client-side, nothing is uploaded.

Steam identifies players in three interchangeable ways:

  • SteamID64 — the 17-digit number (7656…)
  • SteamID3 — [U:1:…] bracket form
  • SteamID2 — STEAM_1:X:Y legacy form

Tools, APIs and admin plugins each expect a different one — this converter handles all three instantly.

How it works

Every SteamID64 shares the constant prefix 76561197960265728 (the base for the account namespace). The remainder is the account ID:

SteamID64 = 76561197960265728 + accountId

SteamID3 is [U:1:accountId]; SteamID2 is STEAM_1:X:Y where accountId = Y×2 + X. All three convert in one line of arithmetic.

Example

STEAM_1:1:617283944: accountId = 617283944×2 + 1 = 1234567889, so SteamID3 = [U:1:1234567889] and SteamID64 = 76561198000000017.

The math behind it

id64 = 76561197960265728 + accountId · accountId = Y×2 + X

Frequently Asked Questions

Why can't this resolve custom URL names?

Converting a vanity name like "sniperpro" to an ID requires the Steam Web API, which needs a server-side key. This page is 100% client-side, so it converts numeric IDs only.

Which format should I use?

SteamID64 is the universal format for modern APIs and Discord integrations. SteamID3 is common in server plugins; SteamID2 is legacy but still appears in older configurations.

Is my ID private?

Steam IDs are public identifiers — they are not private keys. Nothing typed here leaves your browser.
