## About

Stamp DRAFT, CONFIDENTIAL, or your brand across every page — centered or tiled, with a live preview. Local processing, nothing uploaded.

## Quick answer

How do I watermark a PDF for free? Load the PDF, type your text, tune the opacity and angle, and press Add watermark . The live preview shows page 1; the saved file carries the mark on every page. No upload, no account, no per-page work.

## Why watermark at all?

A watermark does two jobs: it labels a document's status (DRAFT, VOID, COPY) and it deters casual reuse of your work — proposals, samples, course materials, and proofs. Doing it by hand in an editor means opening heavyweight software for a one-line stamp; this tool does the whole document in one pass, locally.

## Getting a good watermark

- **Status marks** — DRAFT / VOID / COPY: centered, 45°, 15–25% opacity, red or grey. Visible, but the text underneath stays readable
- **Protection marks** — your name, brand, or order ID: tiled mode at 10–15% opacity. Repeated small marks are much harder to crop out than one big stamp
- **Color logic** — red reads as "not final"; grey reads as "branding"; dark colors at low opacity look like printed stationery
- **Check the preview** — it updates live for text, size, opacity, angle, and position before you commit

## What this tool does and doesn't do

It draws *text* watermarks (any string up to 40 characters) into every page. It does not add image/logo watermarks, per-page different texts, or password protection — for those, pair it with the rest of the PDF family: [rotate pages](https://toolpantry.app/pdf-rotate.html), [delete pages](https://toolpantry.app/pdf-page-delete.html), [merge documents](https://toolpantry.app/merge-pdf.html), or [sign the result](https://toolpantry.app/sign-pdf.html). Everything stays on your device.

## Notes

The preview approximates the final result (exact font rendering happens in the PDF itself). Centered + 20% opacity is the classic "DRAFT" look; tiled mode makes a document harder to reuse.

## FAQ

**How do I add a watermark to a PDF for free?**

Load the PDF, type your watermark text, adjust opacity, rotation, and position, then press Add watermark. The preview shows page 1 live, and the saved file carries the watermark on every page. Nothing is uploaded.

**Can I watermark all pages at once?**

Yes — the watermark is applied to every page in one pass. Choose centered (one diagonal stamp in the middle) or tiled (a repeating grid across the page).

**Will the watermark cover the text underneath?**

At typical settings (15–30% opacity) the watermark sits visibly over the content without hiding it. Use higher opacity for stronger protection, or tiled mode to make the document harder to reuse without attribution.

**Can someone remove the watermark afterwards?**

The watermark is drawn into the page content, so removing it requires editing the PDF — it is not a separate layer you can simply toggle off. For documents that need tamper-proof marking, combine it with a signature or certification service.

**Is my PDF uploaded anywhere?**

No. The PDF is read, watermarked, and saved entirely in your browser. You can verify in the network panel or by working offline.
