Can I add a logo as a watermark?

Yes. Upload any PNG or JPG image (PNG with transparency works best) and position it as a watermark with adjustable opacity.

Will the watermark appear when the PDF is printed?

Yes. The watermark is embedded in the PDF content and will appear in both digital viewing and printed copies.

Can I watermark specific pages only?

Yes. You can apply the watermark to all pages, odd pages, even pages, or a custom page range. This is useful for marking only the content pages of a report while leaving the cover clean, or adding a 'Draft' stamp to just the first few pages.

What opacity should I use for a professional watermark?

For a diagonal text watermark like 'CONFIDENTIAL', 20–30% opacity is the standard professional range — visible enough to deter copying but not so heavy it obscures the content. For a logo watermark in a corner, 40–60% works well. Avoid 100% opacity for text watermarks as it makes the document nearly unreadable.

Can I rotate the watermark text diagonally?

Yes. You can set any rotation angle from 0° to 360°. The classic diagonal watermark uses 45° or –45°. A diagonal orientation is harder to crop out than a horizontal or vertical one, making it more effective as a security measure.

Is it possible to remove a watermark added by this tool?

Watermarks added by this tool are embedded as a content layer in the PDF. While technically removable with advanced PDF editing software, the process is time-consuming and impractical for casual users. For maximum protection, use a diagonal full-page text watermark at 30–40% opacity covering the key content area.
