Watermark PDF: how it works

Questions about Add Watermark
Are files uploaded when I use Add Watermark?
No. PDF Care processes this tool locally in your browser, so the document contents are not uploaded to a PDF Care application server.
Can I change watermark opacity and placement?
Yes. Choose opacity, angle and one of nine page positions before processing the PDF.
Can I watermark only selected pages?
Yes. Apply the watermark to every page, the first page, the last page, or a custom page range.
