LottieLab is an online animation editor based on Lottie technology, designed to simplify the process of creating and editing animations. Lottie, an animation format open-sourced by Airbnb, uses vector graphics and JSON data to deliver high-quality, interactive animations. LottieLab provides an intuitive interface and rich functionality, enabling users to easily create complex animations and customize them by importing and editing existing Lottie files. It supports various layer effects, interpolation animations, path animations, opacity animations, and offers a rich library of animations and preset effects that can be quickly applied to projects. With LottieLab, users can create animations without any coding by dragging and dropping, adjusting parameters, and setting keyframes. The editor also provides real-time preview functionality, allowing users to instantly view and adjust animation effects. Furthermore, LottieLab supports exporting animations as Lottie files, which can be used across various platforms and applications such as mobile apps, web pages, and advertisements. This flexibility enables animation designers and developers to apply animations more flexibly across different environments.
