Based on length and prefix. Several algorithms share a length, so this is a hint, not proof.
About this tool
Paste a hash to see the most likely algorithms. It is a hint based on format, not a guarantee.

Frequently asked questions
Why are there several possibilities?
Different algorithms can produce output of the same length, for example MD5 and NTLM are both 32 hex characters.
