FAQ

What is MurmurHash3?

MurmurHash3 generates a MurmurHash v3 for a string input and an optional seed input. It runs entirely in your browser, so your data stays private.

Is MurmurHash3 free to use?

Yes. MurmurHash3 is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
  • The worked example below could not be pre-computed for this tool (threw: function is not iterable (cannot read property Symbol(Symbol.iterator))); the interactive tool above still works normally.
