Questions
Is Base64 encryption?
No. It only rewrites data as plain characters; anyone can decode it. Don’t use it to hide secrets.
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.
