Are there tools to automatically reduce parts? High-poly -> Low-poly

[Megalodox_Official (Jevangelise)]

Hi, here are some examples of a realistic modeler’s work.

If we have the file, will we be able to use a software to automatically compress it or something?
Thanks for replying!

Try this plugin, it helps convert parts to mesh, and sometimes does in fact turn your high poly parts into low poly, if you enable the setting that increases performance:
