A watermark stamps text or a logo across your PDF pages — "CONFIDENTIAL," "DRAFT," "COPY," or your company logo. It discourages unauthorized use, marks document status, and adds a professional touch. You can add one to every page free in your browser, with a live preview so the result matches exactly what you see.

How to Add a Watermark in 4 Steps
- 1Open the WowShortcuts Watermark PDF tool and upload your PDF.
- 2Choose a text watermark (type your text, pick color, size, opacity) or upload an image/logo.
- 3Pick the position — centered, diagonal across the page, or a corner.
- 4Check the live preview, then download. The watermark is applied to every page exactly as previewed.
A diagonal, semi-transparent watermark (around 20–30% opacity) across the center is the classic look — visible enough to matter, light enough to keep the document readable.
Text vs Image Watermark
- Text: fast and sharp at any size — best for words like CONFIDENTIAL or DRAFT
- Image: use your logo or a custom stamp — best for branding
Private and Applied to Every Page
WowShortcuts adds the watermark in your browser with pdf-lib and applies it to all pages at once. Your document is never uploaded, and what you see in the live preview is exactly what the downloaded file looks like.
