Can I watermark only specific pages?

The current tool applies the watermark to all pages. If you need page-specific watermarks, use the Add Text to PDF tool to place text manually on individual pages.

Is the watermark removable?

The watermark is drawn directly into the PDF page content as a text element — it is not a removable annotation. However, it is not cryptographically secure; a determined person with editing software could attempt to remove it.

Can I use an image as a watermark?

Currently only text watermarks are supported. Image watermarks (e.g. a logo) are planned for a future update.

What opacity should I use?

For a typical 'CONFIDENTIAL' or 'DRAFT' stamp, 15–25% opacity works well — visible enough to notice but not so heavy it obscures the content. Use 40–60% for a bolder mark.
