How to download animated png as lottie

Also, can someone delete my screenshots, please?

I figured it out.

After I created the animation and lowered the duration, I chose add to render queue under composition and outputted to mp4, rendered, and then uploaded the mp4 to Adobe Media Encoder as a png sequence, started the que (the green play icon), uploaded all sequences to After Effects, updated the still duration to 0;00;00;01 and checked sequence layers. I then used the Bodymovin extension where I compressed and included in json under assets, and rendered. Once the json is exported you can add it as a Lottie file. 

As Rick already pointed out, Bodymovin/ Lottie is meant to export vector and animation data as SVGs or HTML canvas, not pixel data. It might be useful if you read the help on the plug-in and on a broader level also educated yourself about web techniques. Most of what you are trying to do here just makes no sense.

After Effects makes video, it does not export Lottie files directly. You need a 3rd party plugin: https://lottiefiles.com/plugins/after-effects

There are severe limitations when you use AE to create graphics for the web. AE is not the most efficient tool for that kind of work. 

Read all the documentation, and you may have some success. You probably cannot export clean code-based files from Particle World because those particles are pixels, not vector art.

Also, I'm new to After Effects and followed this Youtube tutorial: https://www.youtube.com/watch?v=S_kx93-ucWE
