Hello,
Sorry I was not aware of your comment.
> 1) Is it possible to force ratio/crop on upload?
Hawk Vision plugin and Smart Cropped Images Addon may can help it.

When you upload to the image to the media library, they analyze the subject of the image and crop the image to a pre-specified aspect ratio.
> 2) Is it possible to have your plugin work in a frontend form?
No. The images handled by this plugin (and addons) are those uploaded to the media library. Unfortunately, images uploaded by users via the form are not eligible.
> 3) Do you have a version of your plugin that does not require Google API?
The core function of this plugin is to analyze the subject of an image using the Google Cloud Vision API. Therefore, it is not designed to not using the API.
