Remove Recaptcha on unused page

Hey I like the Recaptcha feature of the plugin. But that is adding lot of sizes on my pages. I use the Recaptcha on my both login and register form. But it is also adding sizes to my post pages. I saw the Recaptcha has the highest file size of my site.

You can check this link on pingdom or gtmatrix- https://sitejury.com/review/ysense/

Can I remove that from my post pages. Or other way – can I enable it only form my login or registration form or the url.
