File size increases very much after adding watermark text


After adding a watermark (text) to each page of a PDF Document, the size of the document increases very much. Certain documents have grown 4 times in size. Is there any other strategy of adding the watermark text, but without changing the size of the documents that much?

This is the code, we are using:
//add textstamp to each page
for (int i = 1; i <= info.NumberOfPages; i++)
double angle = CalculatePageAngle(info, i);
foreach (TextStamp stamp in stamps)
stamp.RotateAngle = angle;

Any information would be appreciated.

Thank you in advance.
