About Watermark PDF
A watermark tells the reader what they are holding — a draft, a confidential copy, a sample — and discourages passing it on. Set the opacity low enough to keep the page readable and tile it if the document must not be cropped around.
Frequently asked questions
Can I use my logo?
Yes — choose Image and upload a PNG (transparent backgrounds work) or JPG.
Can the watermark be removed later?
It becomes part of the page content, like any other drawing. Keep an unwatermarked original.
Can I watermark only some pages?
Yes, enter a page range such as 2-10.
