Why watermark a document?
- Protect ID copies: when sharing Aadhaar, PAN or passport copies, add a line like "For bank KYC only – 12 Nov 2026" so the copy can't easily be misused elsewhere.
- Mark status: DRAFT, SAMPLE or PAID on invoices and reports.
- Branding: put your shop, school or company logo on brochures and question papers.
Text in English uses a standard PDF font. Hindi and other scripts, or symbols like ₹, are added as a high-resolution image so they display correctly. Other tools: add page numbers, edit PDF, compress PDF.
