Does Bubble FileUploader & Multi-Uploader compress files

I am creating an app that auto parses a files xmp however for this to work i need the files uploaded to be untouched (not compressed).

In my experience i found that sometimes bubbles FileUploader compresses file uploaded. I was wondering if anyone can comment on what conditions this happens. Also was wondering if anyone new if multi-uploader bubble component compresses files.

Any feedback and clarification on this would be helpful. I believe having this information public and available to the community will also be beneficial as well.

Appreciate the feedback. Have a nice day!
