Frequently asked questions
Can I add my name as a watermark on ID copies?
Yes. Type something like “Only for bank KYC – 12 Nov” to reduce the risk of misuse of your ID copy.
Is it safe to watermark PDFs here?
Yes. Your PDF never leaves your device — all processing happens in your browser, so nobody (including us) can see your file.
Is it free?
Yes, completely free with no sign-up, no watermark and no limits on how many files you process.
Does it work with password-protected PDFs?
No. Remove the password first (open the PDF with its password and save or print a copy without one), then try again.
