About

24px Icon Editor is an AI-built single-page app in the design media category (pixel icon editor). It opens in your browser, so there is nothing to install. You provide pixel clicks and colors and get an icon image. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (simonw/tools).
