Questions
Can someone remove the watermark?
A watermark discourages copying but can be edited out. A repeated pattern across the image is the hardest to remove.
Are my files uploaded?
No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
