Are my files uploaded to a server?

No. Every tool on this site runs inside your browser. Your file is read from your disk into your own browser's memory, processed there, and written back out. You can confirm this yourself: open your browser's developer tools, switch to the Network tab, and run the tool — you will not see your document being sent anywhere. It also means the tools keep working if you go offline after the page has loaded.

Can the watermark go behind the text instead of over it?

Yes. Choose whether the watermark is drawn over the page content or underneath it, so it does not obscure anything you need to read.

Can a watermark be removed later?

A watermark added this way becomes part of the page content. It cannot be toggled off, though someone with PDF editing software could still remove it. Treat it as a label and a deterrent, not as security — use Protect PDF if you need real access control.

Can I watermark only some of the pages?

Not in this tool — the watermark is applied to every page. To mark a subset, use Split PDF to separate those pages out, watermark them, and merge the document back together with Merge PDF.

How to add a watermark to a PDF

1Open your PDFYour first page is shown as a live preview with the watermark drawn on it.
2Write and style your textType the wording, then set colour, size, angle and transparency. Everything updates on the preview immediately, so you are never guessing.
3Choose a layer and applyDraw the watermark over the page, or behind the content so it does not obscure anything you need to read, then download.

When you would use this

A watermark marks intent rather than enforcing it: labelling a version DRAFT so nobody acts on it, stamping CONFIDENTIAL before circulating, or putting your own name across a portfolio or a quote. It is a visible label, not access control, so if you need a document that genuinely cannot be opened or printed by the wrong person, use Protect PDF instead, or as well.
