Watermark a PDF online
Sharing a copy of your Aadhaar, PAN or bank statement with a new employer, landlord or SIM shop? Stamp it with its purpose first. A PDF watermark such as “For KYC only — 6 Oct 2026” makes a leaked copy far less useful for fraud. Businesses use the same tool to mark drafts and confidential reports. Type any text in any language, choose diagonal, centred or tiled, set the colour and transparency, and see a live preview before saving. The file never leaves your device.
How to watermark a PDF
- Choose your PDF.
- Type the text or tap a preset — For KYC only + date fills in today's date.
- Pick the style, colour, transparency and size; watch the preview.
- Tap Add watermark and download.
Which style to choose
| Style | Best for |
|---|---|
| Diagonal | Reports and drafts — clear but doesn't hide the content |
| Centre | Short labels like COPY on certificates |
| Tiled | ID documents — repeated across the page, hard to crop out |
Example
Before emailing your PAN and Aadhaar to a new landlord, merge them with Merge PDF, then watermark the file with “For rental agreement only — 6 Oct 2026”, Tiled, Red, 25% visible. The details stay readable, but the copy is clearly tied to one purpose. Need the file smaller afterwards? UseCompress PDF.
