How to use Add watermark

Drop one or more PDF files on the page.
Choose Text (CONFIDENTIAL, DRAFT, COPY, SAMPLE or My own text) or Picture or logo (PNG or JPG).
Pick the pattern (One centred, Tiled or Grid), the angle and the opacity. The preview updates as you go.
Choose the pages, and whether to put it behind the content.
Click "Add watermark".

Yes. Choose "Picture or logo" and add a PNG or JPG. Set its size as a share of the page width.

Choose Tiled. Its rows are offset like brickwork, which makes it hard to crop out.

Yes. Turn on "Put it behind the content". Text and pictures stay on top, but pages with a solid background hide it.

No. The watermark is added on your device. It is free with no sign-up.
