How is the avatar generated?

The input string is hashed using a simple djb2-style algorithm. The hash bytes determine which cells in a 5×5 grid are filled (mirrored for symmetry) and the hue of the accent color — the same approach used by GitHub identicons.

Will the same input always produce the same avatar?

Yes. The generation is deterministic: the same string always produces the same grid pattern and color, making it suitable as a stable default avatar for users.

Can I use the generated avatar in my app?

Yes, the PNG is generated entirely in your browser and is free to use. You can implement the same hashing logic server-side to generate consistent avatars on demand.

The Avatar Generator creates a unique identicon-style avatar based on a simple hash of any input string — name, email, username, or anything else. It produces a 5×5 symmetric grid (mirrored horizontally like GitHub identicons) with a derived accent color, rendered on a canvas. Download as PNG for use as default profile pictures or placeholder avatars.
