Choose the compression method. Basic compression is completely free and reduces file size by 40%. If you want a smaller file, you can select Strong compression to reduce the file size by 75% (but the file will be of lower quality).

The Strong option is available for a fee - you'll need to sign up for a Pro membership following the site's instructions.

Choosing Basic reduces some of the capacity without affecting file quality much, so this is the right choice for most needs.
