About PDF Watermark Tool

Does this remove existing content?

No. The source pages are copied and the new watermark is drawn over the copied pages.

Can I change watermark opacity?

Yes. Select an opacity from 10 to 80 percent before creating the result.

Is my source PDF changed?

No. You receive a separate watermarked PDF and keep the original file.
