FAQ

What is FNV-1a Hash?

FNV-1a Hash compute the Fowler-Noll-Vo non-cryptographic hash in 32, 64 or 128 bits. It runs entirely in your browser, so your data stays private.

Is FNV-1a Hash free to use?

Yes. FNV-1a Hash 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
