Random, or fixed to a name
Leave the name field empty and every roll gives a new avatar. Type a name or an email address and the avatar is derived from that text alone (trimmed and lower-cased), so “Priya@Example.com” gives the same identicon on every device, every time. That makes it useful for default profile pictures in an app or a test database.
Styles: a mirrored 5×5 identicon, concentric rings, initials on a gradient, a soft blurred orb, and a simple geometric face. Shape can be a circle, a rounded square or a square, with transparent corners.
Reproducible by design
Every image comes from a seed. The address bar holds the generator, the seed, the size and only the settings you changed, so the link redraws the exact same picture on any device. That is useful for picking up where you left off, sending someone a design, or regenerating a file at a bigger size later. See how it works.
