A watermark tells every reader what a document is before they read a word of it: CONFIDENTIAL, DRAFT, SAMPLE, or the name of the person it was sent to. This tool stamps your text onto every page of a PDF in the colour, size and opacity you choose, placed in the centre, diagonally across the page, tiled over the whole page, or along the top or bottom edge.
No, this tool stamps text only. A company name in text works as a brand mark; for an image logo you need a PDF editor that can place images.
Yes, every page gets the same mark. To watermark only some pages, split those pages out first, mark them, then merge the document back together.
Diagonal is the classic DRAFT or CONFIDENTIAL stamp and reads clearly over text. Tiled is the hardest to crop or cover. Top or bottom suits a quiet line such as the recipient's name.
A determined person with a PDF editor can, because it is text added to each page. It deters casual forwarding and makes leaks traceable, especially if each copy carries the recipient's name, but it is not a lock.
