FAQ

About PDF Watermark

Can I add both text and image watermarks to a PDF?

Yes. For a text watermark, set the wording, font size, and a preset color. Image watermarks support PNG and JPG; a PNG with a transparent background is usually better for overlaying document content.

How should I choose watermark opacity, angle, and layer?

Lower opacity obscures less body text, while an angle can create a diagonal identifier. A foreground watermark is more prominent; a background watermark blocks less content. Results depend on page colors and content, so spot-check pages in the live preview.

Can I tile a watermark or apply it only to selected pages?

Yes. Choose a single watermark or a tiled layout and adjust tile spacing. The page range can be all, odd, even, continuous, or custom pages—for example, to exclude a cover or mark only the body.

Can a watermark prevent content from being copied or removed?

No guarantee. A watermark primarily communicates ownership, purpose, or distribution boundaries and is not equivalent to encryption or access control. Use PDF encryption separately if unauthorized opening must be restricted, and keep the source file.

Are PDFs uploaded when adding a watermark?

No. The tool processes multiple PDFs locally in your browser and outputs PDF or ZIP. It does not consume a cloud trial or daily quota.
