Robohash: Auto-Generate Unique Computer-Like Portraits

Discover the fun and customizable algorithm for generating unique portraits from text inputs, often used for identicons or default profile pictures.

What is Robohash?

Robohash is a unique algorithm developed by Jason Long that generates computeresque portraits for any text input. It takes the input text, hashes it, and uses the hash to generate a colorful abstract image uniquely representing that text.

Some key features of Robohash include:

  • Completely customizable - tons of options like size, color, shape, format, etc.
  • Deterministic - the same text input will always generate the same image output
  • Abstract and fun - the portraits don't resemble actual faces but have a cool, computational look
  • Unique identicons - useful as default profile pictures or visual representations of things like user IDs
  • Simple API - easy to integrate into apps to auto-generate user portraits

Robohash is often used on forums, messaging platforms, social networks, and other apps where user-generated content exists. It provides visual distinction between users without needing custom artwork or photos for default pictures. The abstract style gives a fun, harmless anonymity.
