Watermark PDF: how it works
PDF Care renders watermark text locally as a transparent image using the browser font stack, preserving Unicode support. You can then choose position, angle and page scope before the image is embedded into selected PDF pages.

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.
