Convert Account ID to Steam Hex ID
Paste a Account ID below to get the Steam Hex ID straight away. The conversion runs in your browser, so nothing is sent anywhere and there is no sign-in.
Example: 52079950 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 Account ID to Steam Hex ID goes through it:
- Start with the Account ID. It is already the account ID; nothing to do. For
52079950that gives an account ID of52079950. - Build the Steam Hex ID. Add the base, then write the result in hexadecimal. That produces
0x1100001031AAD4E.
Worked example
| Step | Value |
|---|---|
| Account ID in | 52079950 |
| Account ID | 52079950 |
| SteamID64 equivalent | 76561198012345678 |
| Steam Hex ID out | 0x1100001031AAD4E |
What a Account ID is
The bare 32-bit account number underneath every other format. Strip away the base offset and the textual wrapping and this is what remains — the actual identity.
The Dota 2 match history API uses it, several match-history and stats sites key on it, and it is the number shown in a Steam friend invite code. It is also the value you want if you are storing IDs compactly, since it fits in 32 bits.
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.
