Can I customize the watermark text?

Yes — enter any text you like, such as 'Confidential,' 'Draft,' or your company name.

Can I control how visible the watermark is?

Yes — adjust the opacity to make it subtle enough not to obscure the underlying content, or bold enough to be unmistakably visible, depending on your purpose.

Does the watermark appear on every page?

Yes — it's applied consistently across every page of the document in one step, rather than needing to add it page by page.

Is my document uploaded to a server?

No — the entire watermarking process happens locally in your browser, so your PDF never leaves your device.

Can I remove a watermark after adding it?

This tool doesn't include watermark removal — once added and downloaded, you'd need to start from an unwatermarked copy of the original file if you want a version without it.

Will the watermark cover important content on the page?

It's placed diagonally with adjustable opacity specifically so it stays visible without fully obscuring the underlying text or images — review the preview and adjust opacity if it feels too intrusive for your document.

Expert Tips for Watermark PDF

Under vs Over Content: Place watermarks 'Under Content' to keep text legible, or 'Over Content' for security deterrence against copying.
Diagonal Orientation: A 45° diagonal stamp across the page center provides maximum deterrence against unauthorized redistribution.
Vector Typography: Text watermarks render as sharp vector graphics that print clearly at any resolution.
