PDF-XChange products add watermarks (sometimes referred to as "demo stamps") to documents when licensed features are used in evaluation mode. Please ensure that any sensitive documents are saved before using licensed features in evaluation mode, as these watermarks cannot be removed without a valid license.
When using the free version of the software, certain features will add watermarks to a document during actions such as saving, exporting, or optimizing.
This can also occur when using a PDF-XChange Editor license if you attempt to use Enhanced OCR, create Fillable Forms, or generate Dynamic Stamps — these are exclusive to the PDF-XChange Editor Plus and PDF-XChange PRO licenses.
Another common cause is having the incorrect product package installed or not applying your license key. Always ensure you have installed the correct version of the software and entered the appropriate license key. While maintenance is active, you can recover both from your account page, to avoid this issue.
A license must be purchased and applied to your software in order to resolve this issue. Our product pages are available here.
For instructions for adding a new product key see this article.
**Note: If you have not purchased a license or have not entered it, watermarks will be reapplied to the document every time they are removed until a valid license key is entered.**
Once you have Purchased a valid license:
The Document is now cleared of our Demo stamps. In the future, to avoid placing these, ensure that you are only using features which are covered by your license. If you need to purchase a license upgrade to use a new function, please do so from your account page.
