Identicon / Avatar Generator
Generate a unique, deterministic geometric avatar from any text seed.
Type any username, email, or seed text to generate a unique, symmetric geometric avatar - the same seed always produces the same pattern and color, similar to GitHub-style identicons. Download as a PNG for use as a placeholder avatar in apps, mockups, or test data.

The seed text is reduced to a numeric hash, and that single number drives every visual decision: which cells in the grid are filled and what hue the foreground takes. Because hashing is deterministic, the same input always produces the same output, which is the entire property that makes identicons useful as automatic avatars. The grid is generated for one half and mirrored to produce symmetry, which is what turns an essentially arbitrary pattern into something that reads as an emblem. The result is drawn onto a canvas at a higher resolution than the preview so the download stays crisp when displayed at typical avatar sizes. Everything happens locally.

Frequently asked questions
What it can and cannot do, and what happens to your files.
Will the same seed always produce the same identicon?
Yes, the pattern and color are deterministically derived from the seed text.
What determines the color?
The color hue is derived mathematically from the seed text, giving each unique seed a distinct but consistent color.
What size is the downloaded image?
The downloaded PNG is generated at a higher resolution (250x250px) than the on-screen preview.
Why is a deterministic avatar useful?
Because the same user gets the same picture everywhere without anything being stored. A service can generate an avatar from a username at display time, with no upload, no image hosting and no database column, and it will be identical on every device and every page load.
Can someone work out my email from the avatar?
Not from the image itself, since the generation is one-way. But be aware that identicons on many platforms are derived from a hash of your email address, so an identical pattern appearing on two sites does indicate the same address behind both. That is worth knowing if you use different identities in different places.
Why are the patterns symmetric?
Because mirroring one half onto the other makes even random blocks read as a deliberate emblem rather than visual noise. It is the same reason the GitHub-style identicon looks like a small crest: symmetry is what the eye interprets as design.
Is anything I type sent anywhere?
No. The seed is hashed and the image drawn inside your browser tab, so entering a real email address does not transmit it.
