How do I convert SteamID32 to Steam Hex ID?

Paste your SteamID32 into the converter above and the Steam Hex ID appears instantly. Worked through by hand: Multiply Z by 2, then add Y. That gives the account ID back. Add the base, then write the result in hexadecimal. For example, STEAM_0:0:26039975 becomes 0x1100001031AAD4E.

Example: STEAM_0:0:26039975 converts to 0x1100001031AAD4E

How the conversion works

Both formats describe the same underlying account, so the conversion is arithmetic rather than a lookup. Every Steam identifier is built from one 32-bit account number, and the route from SteamID32 to Steam Hex ID goes through it:

Start with the SteamID32. Multiply Z by 2, then add Y. That gives the account ID back. For STEAM_0:0:26039975 that gives an account ID of 52079950.
Build the Steam Hex ID. Add the base, then write the result in hexadecimal. That produces 0x1100001031AAD4E.

Worked example

Step	Value
SteamID32 in	`STEAM_0:0:26039975`
Account ID	`52079950`
SteamID64 equivalent	`76561198012345678`
Steam Hex ID out	`0x1100001031AAD4E`

What a SteamID32 is

The original textual format, written STEAM_X:Y:Z. X is the universe (almost always 0 or 1 for public Steam), Y is the lowest bit of the account ID, and Z is the account ID shifted right by one. Splitting the number this way is a quirk of the original implementation, not something meaningful.

Source engine servers and their tooling still live in this format. SourceMod's admins.cfg expects entries like "STEAM_0:1:12345678", most older ban plugins store it, and the SourceBans web panel has historically rejected newer formats outright. If you administer a Counter-Strike, Team Fortress or Garry's Mod server, this is the one you end up needing.

What a Steam Hex ID is

The SteamID64 written in base 16 rather than base 10. It carries exactly the same information — only the notation differs.

You mostly meet this one in log files, database dumps and a handful of older item and trading tools that stored IDs in hex. It is rarely what a service asks you for, and is usually something you need to convert away from.

Converting more than one ID

This page handles a single ID at a time. To convert a whole list at once — a ban file, an admin config, a spreadsheet column — use the bulk converter, which accepts mixed formats and custom profile URLs in the same paste.
