Can the watermark be removed?

It is drawn into the page content, so it cannot be toggled off in a reader. A determined person with editing software can still remove it — a watermark deters casual misuse, it is not encryption.

Will it cover my text?

Lower the opacity or use tiled mode with a smaller size. The preview shows the exact result before you export.

Are my files uploaded anywhere?

No. Every operation runs inside your browser tab using JavaScript and WebAssembly. Nothing is transmitted to MyToolyard or any third party, and nothing is stored after you close the tab.

Is there a file size or page limit?

There is no artificial limit — the practical ceiling is your device's memory. Files up to roughly 100MB are comfortable on a modern laptop; very large scanned documents are best processed in smaller batches.

Does it work on a phone or tablet?

Yes. The interface is fully responsive and touch-friendly. Very large documents will be slower on mobile because processing uses the device's own CPU and memory.

Add Watermark to PDF — Overview

About this tool

What is Add Watermark to PDF?

Add Watermark to PDF stamps text such as DRAFT, CONFIDENTIAL, SAMPLE or a client name across your pages, with a live preview so you can see the result before you commit.

Everything runs inside the browser, so the sensitive documents that most need a CONFIDENTIAL mark are never uploaded to anyone's server.

You control size, colour, opacity, rotation, tiling and which pages get marked, so the watermark reads clearly without burying the content underneath it.

What it does

What does Add Watermark to PDF do?

Free rotation, including the classic 45-degree diagonal
Tiled mode to repeat the mark across the whole page
Apply to every page or a specific range such as `2-`
Original text, fonts and image quality left untouched underneath

Final thoughts

The bottom line

Watermarking is one of the most common reasons people hand a confidential PDF to an unknown server. Doing it locally removes that contradiction entirely.
