Add Watermark

Stamp a text watermark across every page of a PDF. Great for drafts, confidential documents, or branding.

All tools run entirely in your browser when possible. Files are processed locally and discarded — we never store originals.

Common use cases

  • Stamp DRAFT on a contract before circulation
  • Mark PDF reports as CONFIDENTIAL
  • Add a copyright watermark before sending portfolios
  • Selectively watermark only the cover page

How to use it

  1. 1Drop a PDF and type the watermark text
  2. 2Each thumbnail shows a live preview of the watermark
  3. 3Click pages to skip them (the watermark won't appear there)
  4. 4Click Apply — your watermarked PDF downloads

Add diagonal text watermarks to any PDF. The live preview shows you exactly where the watermark will land on every page before you download.

Frequently asked questions

Are my files uploaded to your servers?

Most operations run client-side — your file never leaves your browser. The few that need server compute (compress, server-side rasterisation) discard the file the moment processing completes. We don't store originals.

What's the difference between Free and Pro?

Free covers most one-off needs: one PDF/image/OCR operation per day across the toolkit, plus the basic features of every tool. Pro removes the daily limit, unlocks batch operations, premium templates, advanced customisation, multi-language OCR, ICO + PWA exports, and more.

Do I need an account?

No — every tool on this page works without an account. Pro features and the broader generators (proposals, contracts, resumes, time tracker) require sign-up.

What's the maximum file size?

Most PDF tools accept files up to 25 MB. JPG/PNG inputs are capped at 15 MB per file. If you need higher limits, Pro raises the ceiling.
