I would like to know which API, library, or technology should I use in order to compress and resize video uploads in these formats : mp4, mov, webm to aspect ratio dimensions 16:9 and 9:16 so that videos are way smaller that when were uploaded initially. I am using Wordpress.
If you need a simple online tool for it rather than API, try using it: Ssemble video compressor as well (search for it on Google).
Very nice to see this post you can take guide from electronic air compressor page where they are telling everything about it.

Thank you Blinov!
https://zencoder.com/en/file-transcoding/features --- this actual site hasn't been updated in years, but powers many saas video platforms. Source --- I used to work at brightcove.
We're using Cloudinary: https://cloudinary.com
They also have a wordpress plugin: https://wordpress.org/plugins/cloudinary-image-management-and-manipulation-in-the-cloud-cdn/
It's the swiss army knife of image and video transcoding.
Yes it looks a great wp plugin, unfortunately it only works for images
i used this: https://nl.converterpoint.com/
works fine.
