allowImageTransform=true causes significant file size growth

Describe the bug

When allowImageTransform=true (or omitted, as true is the default) the file size of the image (.jpg and .png tested) increases substantially (one test turned a 558KB file into a 3.9MB file). Setting allowImageTransform=false prevents this.

It appears that the image was automatically being drawn to canvas and exported which was adding an Alpha channel and causing the file size expansion.

Reproduction

Set allowImageTransform=true (or omit it) and upload a file to the server. Compare the original file size to the uploaded file size.
