Why watermark ID copies
Writing the purpose and date on a copy of your Aadhaar, PAN or passport ('For flat rental, Oct 2026') makes it much harder to misuse the copy for anything else. It takes ten seconds here.
Private by design
Most online converters upload your file to a server, process it there and send it back. That is slow on mobile data and means a copy of your document sits on somebody else's computer, at least for a while. This tool works differently: the code runs inside your browser, so the file is read and processed on your own phone or laptop and is never uploaded. That makes it a good fit for bank statements, ID scans, offer letters and anything else you would rather keep private.
