Frequently asked questions
Is adding a watermark to a PDF online really free?
Yes. There's no account, no subscription, and no limit on how many times you can use it. The site is supported by advertising rather than fees.
Can I control where the watermark appears?
Yes — choose a diagonal stamp across the center of the page, or a smaller mark tucked in a corner, and adjust its size, color, opacity, and rotation angle.
Does the watermark get added to every page?
Yes, by default it's stamped on every page of the document, matching what most watermarking tools do.
Are my files uploaded to a server?
No. Everything happens directly in your browser tab — your file is never sent anywhere, and we never see its contents.
Can I remove the watermark afterward?
Once it's stamped onto the page and saved, the watermark becomes part of the page content, the same way it would with any watermarking tool — so keep your original file if you might need an unmarked copy later.
