Is it possible to further restrict asset filetypes than just "image"?

For example only allow .jpg, .jpeg and .png ?

It depends. If the only files you want to upload are .jpg, .jpeg, and .png, then yes: set allowedFileExtensions in your config/general.php

'allowedFileExtensions' => 'jpg, jpeg, png',

If you want those to be the only image filetypes, but to allow other files for non-image assets, then that is harder (and I don't know how to do it).
