128KB is a platform and a framework, celebrating code-based creative work within tight technical limits.
Rule 1: 128KB filesize max
Our defining constraint.
Rule 2: 128 pixels max
Your submission can have any aspect ratio, but 128 pixels max on each side.
Common Formats
- 9:16 – 72 * 128px

Rule 3: Made with Code
128KB is for artists and designers who write code. Your submission must be generated or rendered through code you’ve written.
Rule 4: Gif Format
GIFs are lightweight, universally accessible, and ideal for small, expressive animations.
