Built this for discord because compressing/resizing lottie files is a pain.
npm install
You can use any tgs (gzipped Lottie) or .json/.lottie/etc file.
$ node . ./cutesticker.tgs
or
$ node . ./cutesticker.json
etc. etc.
will output an APNG file called ./cutesticker.png
If it's too big, try compressing it with this tool https://tinypng.com/
If it's still too big, you could remove every 2nd frame and double the delay using this tool https://ezgif.com/apng-maker
This uses puppeteer-lottie, so it's kinda bloated atm. Feel free to PR an alternative.
