    Why watermark

    Mark ID copies you submit with their purpose ('Copy for XYZ Bank KYC only, 29/09/2026') so they can't be reused elsewhere. Mark drafts so they aren't mistaken for final versions, and add CONFIDENTIAL to documents you share for review.

    Readable and unobtrusive

    Choose the opacity (15% is faint but visible), the colour and whether it runs diagonally corner to corner. The watermark's size adapts to each page, including landscape pages, and it's drawn above the content so it can't simply be hidden behind a picture.

    Watermarking ID proofs

    For Aadhaar, PAN or passport copies, write the purpose and date as the watermark, and also redact numbers you don't need to share. Then set a password if you're emailing it.

    Use cases

    Drafts and confidential copies

    Stamp DRAFT or CONFIDENTIAL across every page before circulating a document.

    ID copies as PDF

    Write the purpose and date across a PDF copy of your ID before sharing it.

    Branding documents

    Put your company name faintly on quotations, brochures and reports.

    How it works

    1. Open the PDF and press Document (the page icon).

    2. Under Watermark, type the text and choose opacity, colour and direction.

    3. Download the watermarked PDF.

    Questions

    Can the watermark be removed?

    It's part of the page, so it can't be switched off, though anyone with an editor can try to cover it. For sensitive copies, add the purpose and date.

    Can I use my logo as a watermark?

    Use Image to place your logo on a page. For a logo on every page, use the Watermark tool for images.

    Will it cover the text?

    At low opacity the text underneath stays readable.

    Can I watermark only one page?

    The watermark goes on all pages. For one page, use Add text with a large faint colour instead.
