Image Intervention not doing anything

I installed the intervention package, and I get no errors at all. But the image is unmodified. Here's my code:

use Intervention\Image\Facades\Image;

...

if ($request->hasFile('avatar')) {
            $avatar = ($this->generateImageFileName($request->file('avatar'), 'users'));
            $request->file('avatar')->storeAs('public', $avatar); //Upload Avatar
            //dd($avatar);
            Image::make('storage/'.$avatar)->fit(600); //resize to 600x600
            $user->avatar = $avatar; //Write to DB
        }

If I dump the Image::make line, I get this:

  #driver: Intervention\Image\Gd\Driver {#334 ▼
    +decoder: Intervention\Image\Gd\Decoder {#335 ▼
      -data: null
    }
    +encoder: Intervention\Image\Gd\Encoder {#336 ▼
      +result: null
      +image: null
      +format: null
      +quality: null
    }
  }
  #core: gd resource @509 ▼

  }

}

To install, I ran composer require intervention/image, added the service provider and facade alias as mentioned in the docs and ran composer install, just to be sure. Is there something I'm missing?
