How to Watermark a PDF
Choose text or image mode, set opacity, angle, position and page selection, then export. Watermarks are placed over existing content and the original page is not rasterized simply to add the overlay.

The interface is designed to keep the active PDF workflow near the top of the page, while this guide explains what the tool changes, what it preserves, and where a different PDF tool is the safer choice.
Text vs Image Watermarks
Text mode is useful for labels such as DRAFT or CONFIDENTIAL. Image mode is better for logos and stamps. PNG transparency is retained when supported by the source image.

Opacity and Rotation
Low opacity makes a watermark less intrusive. Diagonal angles are common for document-status marks, but rotation is user controlled rather than fixed.

Selected Pages
Watermarks can be applied to all pages, first or last page, odd or even pages, or a custom range. The output reports how many pages were modified.

Repeated Watermarks
Repeat mode generates a bounded grid using sensible spacing. The implementation limits tile counts to avoid accidental thousands of overlay items.

Quality and Privacy
Text watermarks are PDF text and image watermarks are embedded images. The rest of the page remains source PDF content, and the watermark text or image is not sent to a remote service.
