Step by step

How To Watermark a PDF

Stamp your words or a picture across the document — live, so you see the exact mark before you run it. Every page, or just the ones you pick.

  1. 1

    Upload your PDF

    Drop in a document and the watermark editor opens with a sample mark already on page 1. Three ways to start: Add Text writes a watermark, Add Image places your logo or a stamp, and Templates brings back a setup you saved before. Files are deleted after 2 hours.

    Make it yours

    Click the mark on the page to type your own words right in place, or write in the Watermark text box — one text per line makes a version for each, for batch runs. The strip on the mark adjusts Opacity, Color, Recenter and Font; the panel sets Location on page (Centered, or Custom with edge distances), Rotation, and Style — font, size and colour.

    Pick pages and apply

    Leave it on every page, or name ranges like 2-3,5 — perfect for stamping “Draft” on one section. Preview page flips the editor to the sheet you want to check. Press Watermark PDF and the stamped file comes back ready to download; Save settings remembers the whole setup for next time.

  • Type it in place

    Click the mark and type — you edit the watermark right on the page.

  • Text or image

    Write a word, or place a logo or stamp picture as the watermark.

  • Any colour, any fade

    Pick from the palette or paste a hex, and set the opacity from 1 to 100.

  • Rotate freely

    0–360° — the classic diagonal, or any angle your stamp needs.

  • Saved templates

    Set the watermark up once, name it, and reuse it on any document in one click.

  • Private by default

    No account, no watermark — and every file is automatically deleted after 2 hours.

Watermark — frequently asked questions

Can I watermark only some pages?

Yes — set pages like 1-3 or even and the mark lands only there. Text or image, any colour, size, rotation and opacity, over or under the content.

Is Watermark free?

Yes — Watermark is free right here in your browser, with no watermark and no sign-up. Every tool on the site works the same way.

Do I need an account to use Watermark?

No. Accounts are optional — they keep your credits, API keys and settings together. The tools work signed-out.

What happens to my file?

Every upload is stored under an unguessable id and deleted automatically after 2 hours. Nothing is listed, shared or emailed anywhere.

Can I run Watermark from the API?

Yes — every tool has a REST endpoint. An API call for this tool costs 10 credits per file; browser use stays free. See the Plans & pricing page for plans and the API page for the endpoint list.
