What watermarks accomplish
They attach context that survives forwarding: whose document this is, what status it carries, who it was prepared for. A proposal watermarked with the client's name discourages the classic forward-to-competitor move.
Legible page, visible mark
The craft is opacity and placement — diagonal, translucent, behind the reading. A good watermark is unmistakable and unobtrusive at once; the tool\'s controls put that balance in your hands. Files are processed temporarily and deleted automatically — there is no general cloud storage.
