A visible watermark is the simplest way to signal that a document is still a draft, is confidential, or belongs to a particular organisation. Diagonal text across every page makes the status hard to miss and discourages accidental misuse.
Typical situations that need a watermark
- Marking a proposal or report as DRAFT before internal review.
- Labelling sensitive internal files CONFIDENTIAL before limited distribution.
- Adding a company name or SAMPLE mark to portfolio pieces shared publicly.
- Preventing a preliminary design proof from being treated as final.
Choosing opacity and wording
Text that is too dark fights with the content underneath; text that is too light can disappear in a print or scan. A moderate opacity (around 25–40 %) usually strikes the right balance. Keep the wording short — CONFIDENTIAL, DRAFT, SAMPLE, or a short company name — so it remains legible when applied diagonally.

Try the Add Watermark ToolWatermark versus real security
A text watermark is a visual label, not encryption. It does not stop a determined person from copying the content. For actual access control you still need password protection or a proper document-rights system. The watermark’s job is simply to make the document’s status obvious at a glance.
Privacy reminder
Documents that need a “confidential” mark are by definition sensitive. Prefer a tool that draws the watermark locally in the browser so the file itself never travels to a remote server.
