Add Watermark to PDF

Stamp draft, confidential, or branded text across each page locally in your browser. Keep the file private while marking it clearly.

Quick answer

Choose a watermark that is easy to see but still lets the page content breathe, then preview a couple of pages before exporting.

Step 1

Use simple text for draft and confidential marks, or a light logo if you want branding. Keep the message short and readable.

Step 2

A centered diagonal mark usually works for drafts. For formal files, use a lighter position so the watermark does not hide labels or charts.

Step 3

Check the first page, a middle page, and the last page to make sure the watermark stays consistent across the file.

Using a watermark so dark that the page becomes hard to read.
Choosing a message that is too long to fit cleanly on every page.
Forgetting to verify how the watermark looks on pages with dense charts or narrow margins.

Add watermarks & page numbers.

Basic annotations & signatures (privacy-focused, limited features).

Draw, type, or upload a signature.

Change the filename for humans, then update the embedded metadata so search, archives, and document viewers show the right details.

Select the pages you do not need, remove them locally, and export the trimmed PDF once the remaining pages look right.

What should a good watermark say?

Keep it short. Draft, Sample, Confidential, or a simple brand mark usually works best.

Can I watermark the whole file at once?

Yes. The watermark workflow applies the mark across the selected pages and exports a new copy.

Will watermarking upload my file?

No. The file stays in your browser while the watermark is added locally.

If you want to do the task now, open the matching tool and keep the files local in your browser.
