PDF Watermark
Stamp text like DRAFT or CONFIDENTIAL across a PDF, with control over opacity and angle.
A label that travels with the document
A watermark quietly sets expectations before anyone reads a word. DRAFT stops an unfinished proposal being mistaken for the final version; CONFIDENTIAL flags a sensitive file; your name or company across a document marks ownership. It sits over every page without hiding the content underneath.
Type your text, set the opacity and angle, and it is applied across the document.
Keep it readable
Restraint is the whole trick. A watermark cranked to full opacity makes the document hard to actually read, which defeats the point. Light grey text on a slight diagonal is visible without fighting the content. If you have a stack of files to mark rather than one, doing them as a batch applies the same stamp to all of them at once.
Frequently asked questions
Can I control how strong the watermark looks?
Yes — adjust the opacity and angle so it is visible but does not overpower the text.
Does it go on every page?
Yes, the watermark is applied across the whole document.
Is this the same as locking the PDF?
No. A watermark labels a document; it does not restrict access to it.
