The Lottie Animation Format is a vector format focused on animation, interaction, real-time updates and multi-platform support. This document describes the specifications of the format and its extensibility. It will also describe how to specify supported layer types and properties.

Given its objective of being a global animation vector format, the Lottie Animation Format does not focus on performance improvements for a single platform. Instead it tries to be as simple and extendable as possible.

The format is influenced by the Adobe After Effects Render Model, from which it draws the layer, keyframes, and properties structure.

This specification defines a model for drawing and animating a set of layers on a canvas.
