A label that travels with the document
A watermark is pale text printed across a page. It tells anyone who opens the file what they are looking at. A quote that is not confirmed yet can say "DRAFT", study notes can carry the author's name, and a passport copy sent to a travel agency can state who it is for – "For trip booking only", for example.
Three positions
- Diagonal – one line across the middle of the page, tilted along its diagonal. This is the default.
- Horizontal – one line, level, in the middle of the page.
- Tiled – the same text, slightly slanted, repeated in rows over the whole page.
With the first two, text that is too long is shrunk automatically until all of it fits on the page. With "Tiled" the size stays as entered, so start with smaller letters.
Look and coverage
The text can be up to 80 characters. Until you change anything it reads "CONFIDENTIAL", in red, at size 60 and 25% opacity. Size goes from 10 to 200 and opacity from 5 to 90%; a lower percentage means a fainter mark. The font covers accented Latin letters and Cyrillic. An empty "Pages" field marks every page; to mark only some, list numbers and ranges such as 1-3, 5.
How much it protects
The watermark becomes part of the page content, but it is not a lock: someone with the right software can sometimes remove it. "Tiled" is the hardest to deal with. If the file should not be opened by just anyone, lock it with Protect PDF.
The watermark is added in your browser, so the document is not uploaded to SnoopyWap. Your original file is not changed. Need numbers on the pages too? Use Page numbers.
