How it works
Choose a text or image watermark, its position on the page, opacity, and rotation. The watermark is drawn on every page (or a selected subset) as a semi-transparent overlay. Original content stays intact underneath.
Common use cases
- Marking a draft or confidential document with a diagonal "DRAFT" or "CONFIDENTIAL" stamp before sharing.
- Adding a company logo to every page of a proposal or a portfolio.
- Watermarking a document sent to a client so screenshots trace back to that specific recipient.

FAQ
Can I remove the watermark later?
The watermark is embedded as part of the page content. Standard tools can't easily remove it, but a determined user could re-render the page as an image and try to inpaint it out. For a lock, combine with Flatten PDF and a strong password via Protect PDF.
Does it affect selectable text underneath?
No. The watermark is drawn as a separate layer above the page — the original text remains selectable and searchable.
