A mark that survives being sent

The reason to watermark is that a document is going somewhere it might be mistaken for something it is not: a draft read as final, a quote read as an invoice, an internal paper forwarded outside. DRAFT, CONFIDENTIAL, COPY and a client name are the marks that do that work.

Word has a watermark button and Excel has none, and the Word one has a flaw people rarely think about: the watermark is an object in an editable document, so the first thing the recipient can do is remove it. Applied here it becomes part of the page, so it prints, it survives forwarding, and there is nothing to delete.

Getting the weight right

Too dark and the document becomes hard to read, which people work around by ignoring the watermark entirely. Too faint and it does not register at all. Look at it on the busiest page rather than the title page, because that is where a heavy watermark does its damage.

An image works as well as text. A pale logo behind the content reads as letterhead; a strong one reads as a stamp. They send different signals, so choose deliberately rather than by default.

Frequently asked questions

Is the watermark tool free?

Yes. Adding a watermark to a PDF is completely free, with no signup. Your file is processed in your browser and never uploaded.

Can I control the watermark opacity and angle?

Yes. You can set the text, colour, font size, opacity, and rotation so the watermark sits exactly how you want across every page.

Will the watermark appear on all pages?

Yes. The text watermark is applied to every page of the PDF in a single step.

Can I watermark every page?

Yes, and for a draft you should, because pages get printed and separated.

Can the recipient remove it?

Not without altering the document. It is part of the page rather than an object sitting on top of it, which is the difference from a Word watermark.

Can I use my logo instead of a word?

Yes. Upload the image and set how faint it should be.
