About Identicon Generator — Avatar, Gravatar Alternative

An identicon is a small, visual fingerprint generated from a seed string — a username, email, or hash. The same seed always produces the same symmetric image, which makes identicons a great drop-in for default avatars and a quick way to tell accounts apart at a glance.

This identicon generator turns any seed into a deterministic, vertically-symmetric SVG avatar. It's a self-hosted gravatar alternative: there's no account, no upload, and no network call — your seed is hashed locally and rendered right in the browser. Copy the SVG markup or download the result and use it wherever you need a default avatar.

Features

  • Deterministic — the same seed always renders the same avatar
  • Crisp, scalable SVG output at any size
  • Symmetric grid + auto-derived color from the seed
  • Fully offline: the seed never leaves your device

How to use

  1. Type a seed — a username, email, or any string.
  2. Adjust the size if you need a larger or smaller avatar.
  3. Preview the identicon and copy the SVG markup, or download it.

Frequently asked questions

What is an identicon?

An identicon is an image generated deterministically from a string. The same input always yields the same picture, so it works as a unique visual fingerprint or default avatar without anyone having to upload a photo.

Is this a Gravatar alternative?

Yes. Gravatar maps an email hash to an avatar on a remote service. This tool does the same mapping locally and offline — no account, no upload, and the seed never leaves your browser.

Why does the same seed always look the same?

The seed is run through a fast deterministic hash (FNV-1a). The hash bits choose both the color and which grid cells are filled, so identical seeds produce byte-for-byte identical SVGs.

Is hashing the email or username secure here?

The hash is for visual variety, not security — it isn't cryptographic and shouldn't be treated as a way to hide the seed. Everything runs locally, so nothing is transmitted, but don't rely on the identicon to conceal the underlying value.

Everything runs locally in your browser — your input is never uploaded.
