Avatar Generator

Generate deterministic avatars from a seed string. Initials, geometric, or identicon styles. SVG output, downloadable.

01 — Overview

How the Avatar Generator works

Type a name, email, or any seed string and get a consistent avatar for it. Three styles: initials (with auto-colored backgrounds), geometric (gradient + shape), and identicon (5×5 mirrored pattern, GitHub-style). Output is SVG for crisp scaling.

02 — Use cases

When to use the Avatar Generator

  1. 01

    Generate placeholder avatars for a user table in a fresh app

  2. 02

    Mock up a comment thread with consistent per-user avatars

  3. 03

    Seed a demo with avatars that won't look like stock photos

  4. 04

    Add a fallback avatar for users who haven't uploaded one

03 — Examples

Avatar Generator examples

Jane Doe (initials)

ex 01

JD on a hashed teal background

Initials avatar with a background color derived from the seed.

alex@example.com (identicon)

ex 02

5×5 mirrored pixel pattern in two colors

GitHub-style identicon, deterministic per email.

Acme Corp (geometric)

ex 03

Gradient tile with a deterministic shape, derived from the seed string

Works for organizations as well as people, where initials would read oddly.

user_8823 (identicon), 64px

ex 04

5×5 mirrored pixel pattern in two hashed colors

Stable per seed, so the same account keeps the same avatar across sessions.

04 — FAQ

Avatar — frequently asked questions

Is the same seed always the same avatar?

Yes. The seed is hashed and used to drive color and shape choices, so the same input always produces the same avatar — useful for fallback rendering in a production app.

Can I use these in a commercial app?

Yes. The avatars are generated locally and contain no third-party assets. Download the SVG and ship it.

How is this different from Gravatar?

Gravatar looks up a real, user-supplied avatar by email hash. This tool generates a synthetic avatar from any seed — no network call, no per-user data.

What alt text should a generated avatar have?

If the person's name appears next to the avatar, the image is decorative — use alt="" so screen readers don't announce the name twice. If the avatar stands alone, as in a compact activity feed, give it the person's name as alt text.

Should I use the SVG or a PNG?

SVG for anything on the web — it's a few hundred bytes, stays crisp at any size, and scales with the container. Rasterize to PNG only where SVG isn't reliably supported, which in practice means email clients and some PDF pipelines.

Will the initials always be readable on the generated background?

The background color is derived from a hash of the seed, and the foreground is picked to clear the WCAG 3:1 threshold for large text against it. If you override the background manually, check the pair yourself — a mid-tone background is the easy way to end up with unreadable initials.
