Can I use an image as a watermark?

Yes — upload a PNG or JPG alongside your PDF and it will be stamped on every page at your chosen opacity and position.

Will the watermark appear on every page?

Yes, the watermark is applied to every page of the PDF.

Are my files uploaded to a server?

No. Watermarking runs entirely in your browser using pdf-lib. Nothing leaves your device.

Can I remove the watermark later?

Text watermarks added by this tool are embedded in the page content stream. They cannot be removed with a simple click, but dedicated PDF editors can strip content layers.
