If you’ve ever worked with Microsoft Entra ID (formerly Azure AD) and had to deal with SIDs or Object IDs, you know how annoying it can be to figure out which one belongs to what. Especially in hybrid environments, where on-prem AD identities are synced to Entra ID, you’re constantly juggling SIDs and Object IDs—and nobody tells you which one maps to which.

That’s exactly why we built this handy Online Tool: a simple converter that tells you, in seconds, which SID belongs to which Object ID—and vice versa. No more copy-pasting from obscure logs, no more poking around in portals. Just fast, clean results.
