About this tool
Sharing Aadhaar, PAN or property papers? A watermark like “For bank KYC only” makes misuse much harder. Set the text, colour, size, transparency and angle, or upload your company logo as a PNG with a transparent background.
English text is added as real PDF text. Text in Hindi and other Indian scripts is drawn with your device’s fonts and added as a transparent image, so it displays correctly everywhere.
Frequently asked questions
Can I write the watermark in Hindi?
Yes. Non-English text is rendered with your device’s fonts and embedded as an image, so it looks right in any PDF reader.
Can someone remove the watermark?
A determined person with PDF editing software might. For stronger protection, combine a watermark with a purpose-and-date note in the text.
What image works best as a logo watermark?
A PNG with a transparent background. Lower the opacity to about 15–30% so the document stays readable.
