At the moment, Uploadcare does not have a built-in zoom out option, but it is on our roadmap.
As a temporary workaround, we suggest using two crop options: free + crop preset.
The final result will look like this:
If you want the image to fit into your size limits, you can add force crop to fix size. For example,
<input type="hidden" role="uploadcare-uploader" name="my_file" data-crop="400x300 upscale" />
See crop documentation for details.
