What is a lottie / JSON file?

A Lottie file is a lightweight, JSON-based file format used to deliver scalable, high-quality animations. It renders vector animations, making them resolution-independent and perfect for seamless integration into apps, websites, and digital platforms. Created in tools like Adobe After Effects and exported via plugins like Bodymovin, Lottie files are small in size, highly performant, and allow interactive, visually appealing animations without sacrificing speed or quality.
