Lottie is a lightweight animation format that allows you to render vector animations in real time across web, mobile, and desktop platforms. It's based on JSON and was developed by Airbnb to bring high-quality, scalable animations to apps without sacrificing performance.
Format
We are following the official Lottie specifications.
Lottie animations can be exported in two formats: JSON and dotLottie.
dotLottie
dotLottie (.lottie) is an advanced file format designed to package Lottie animations into a single, efficient, and portable compressed file. It improves the way Lottie animations are shared and used by bundling multiple assets into a single archive file.
Limitations
Even though lottie is a very promising format, it still has some limitations compared to SVG. Below is a list of such limitations:
Gradients
- Spread method is not supported.
- Aspect ratio property is not supported if different than ±100%.
- Out of radius highlight is not supported for radial gradient with focal point.
- Focal radius greater than 0 is not supported for radial gradient with focal point.
Filters
- Color Adjust filter is not supported.
