Watermark PDF

Frequently asked questions

Can I control how visible the watermark is?

Yes — set the opacity along with the colour and size, so you can make it a bold stamp or a subtle overlay that doesn’t obscure the text underneath.

Does the watermark go on every page?

Yes, the same text, colour, size, opacity and position are applied to every page of the PDF in one pass.

Can I use a logo image instead of text?

This tool stamps text watermarks. For placing an image or logo on a page, use the PDF Editor or PDF Sign tool instead.

Is my PDF uploaded or stored anywhere?

It is processed to produce the watermarked file and not kept afterward — there is no account and no storage.

Do I need to install anything or sign up?

No. It runs entirely in your browser and our server — no software install, no account, no email required.
