Helpful answers
PDF Watermark FAQs
Are my PDFs uploaded?
No. ToolNest reads the PDF, draws the watermark, and creates the download inside your browser. The PDF is not uploaded to ToolNest or a conversion server.
Can I watermark only selected pages?
Yes. Apply the watermark to every page or enter page numbers and ranges such as 1-3,6,8-10.
Can I control watermark opacity and angle?
Yes. Choose the watermark opacity and select a horizontal, diagonal, or vertical angle before creating the PDF.
Does adding a watermark flatten the PDF?
No. ToolNest adds text to the existing PDF pages with PDF drawing commands rather than rasterizing each page. Existing selectable text and vector content are preserved where the PDF library supports them.
Can this tool remove an existing watermark?
No. This version only adds new text watermarks. It does not remove or edit watermarks that are already present in a PDF.
