Bodymovin is an open-source plugin for Adobe After Effects that allows users to export animations as JSON files. This enables the animations to be rendered natively on the web using the Lottie library, which is designed for high-quality, lightweight animations. By converting complex animations into a format that can be easily integrated into websites and mobile applications, Bodymovin enhances user experience and engagement. It supports various features like shape layers, masks, and text, making it a versatile tool for designers and developers looking to incorporate animations seamlessly.
