Why add a watermark to a PDF?

A text watermark marks a PDF as a draft, confidential, or the property of a specific person or company, and discourages unauthorized copying or redistribution. It's commonly used on contracts, proposals, internal reports, and shared drafts before a document is finalized.

PDFly adds the watermark directly in your browser, and your file isn't uploaded anywhere. There's no account to create and no software to install. It works on Windows, Mac, Linux, Android, and iPhone using any modern browser.

Frequently asked questions

Can I control where the watermark appears?

Yes. Choose from center (diagonal), or any of the four corners or top/bottom-center positions, and set the rotation angle independently.

Will the watermark appear on every page?

Yes, the watermark is applied to every page of the PDF using the text, size, color, opacity, and position you set.

Can I make the watermark subtle instead of bold?

Yes. Lower the opacity to make it faint, or reduce the font size so it blends into the page without obscuring the content.

Is my PDF uploaded anywhere?

No. The watermark is added entirely in your browser, and the file isn't uploaded anywhere.
