Lottie Files

Lottie Files are a fantastic way of adding moving graphics to your WordPress site, and many of the animations found in the library are completely free to use.

There is even a WordPress plugin made by LF that makes finding and embedding animations onto a page super simple.

Plus the overhead on page loading times when using Lottie Files is much lower than standard animation files (GIF, MP4) as their framework instead uses JSON to load the assets (but those other file types are still available if required).
