Is there a way to change the image sizes from the products? for small_image, thumbnail from Magento 2.3

When retrieving from Magento 2.3 to be used in vanilla php, I see in the attributes retrieved for image, small_image, and thumbnail all retrieve from the same source rather than different sizes. Is there a way or am I missing something to retrieve different sizes for the images?

<media_gallery_entries>
<item>
<id>157109</id>
<media_type>image</media_type>
<label>11005_1</label>
<position>1</position>
<disabled>false</disabled>
<types>
<item>image</item>
<item>small_image</item>
<item>thumbnail</item>
</types>
<file>/1/1/11005_1_1.png</file>
</item>
</media_gallery_entries>



<item>
<attribute_code>small_image</attribute_code>
<value>/1/1/11005_1_1.png</value>
</item>
<item>
<attribute_code>options_container</attribute_code>
<value>container2</value>
</item>
<item>
<attribute_code>thumbnail</attribute_code>
<value>/1/1/11005_1_1.png</value>
</item>

I want the image thumbnail and small image to be much smaller than the actual image when loading a gallery.
