PDFsharp watermark can be remove!!! #176

When the watermark is added to a pdf and saved successfully. If you convert that pdf file to a word using any conversions tool like "https://www.ilovepdf.com/pdf_to_word".

The watermark can be removed when opened in word.

Is there any way to make the pdf with the watermark stick together like one image??

The best you can try is setting an owner password. But this will not stop all tools from manipulating the file.

Thanks, It worked with setting the owner's password. However, as you mentioned, this won't stop all tools from cracking it. Therefore, does your library provide pdf to HTML conversion?

PDFsharp cannot render PDF in any form, including HTML.
