Do you guys have a good online tool, command line tool or a Node.JS library to compress videos?

I would like to put a video I made today on a customer website, but I filmed it in 4k so for 15 sec. it weights 44MB 😂

The best tool that I am looking for would:

• Trim useless bytes
• Create variants by size (like 600x?, 980x?, 1200x?, 1920x?) with the ability to choose the sizes
• Create a webm counterpart of the video (not necessary, but appreciated)

Anyone?
