A watermark stamps text — like DRAFT, CONFIDENTIAL, or your company name — across every page, with control over opacity, angle, and position so it's visible without burying the content.

Frequently asked questions
- Can I make the watermark semi-transparent?
- Yes. The opacity control lets you fade it so the document underneath stays readable.
- Can I angle the text diagonally?
- Yes. Set any rotation angle — a 45° diagonal is the classic “DRAFT” look.
- Does the watermark apply to every page?
- Yes, it's stamped across all pages so no page is left unmarked.
- Can the watermark be removed later?
- Once applied and downloaded, the text is part of the page content, so treat it as permanent. Keep your original if you'll need an unmarked copy.
- Are my files uploaded?
- No. Watermarking happens locally in your browser.
