Add Watermark: practical notes
What stamping a watermark actually does
The tool draws your text or image on top of each page as visible content, like DRAFT, CONFIDENTIAL, or a logo. It sits over the existing page, so the original text and graphics stay underneath, unchanged. This is plain marking, not encryption or copy protection: a determined person can still crop the page or edit it to strip the mark out.
Set opacity and position so you do not hide text
A watermark is meant to be seen without burying what is below it. Keep the opacity low enough that the page text stays readable through it, and place the mark where it does not cover important lines, figures, or signatures. A faint diagonal stamp across the center usually reads clearly while leaving the content legible.
When a watermark is the right tool
Use it for branding, marking a document as a draft or confidential, and discouraging casual reuse of your work. It is good at signaling ownership and status at a glance. It is not a security control: if you need to actually stop opening, copying, or editing, use password protection or encryption instead, since a visible stamp can be removed.
Privacy and what to expect
Everything runs in your browser, so your file never leaves your device, which suits contracts, IDs, and other private documents you would rather not upload. Because the mark is layered visible content, treat it as a deterrent and a label, not a lock. Pick a clear word or logo, a low opacity, and a position that leaves your page readable.
