Watermark before purchasing

Dears ,
I used the free license to convert pdf to word and i got the watermark in the top of all documents, so i purchased a license and i want to know if this watermark will disappear or not for the old documents?

@amal88,

Thanks for contacting support.

I like to inform that there will be no watermark if you apply proper license in your code to generate files.

I mean for the old documents that i have already converted with the free license , i still can see the watermark.

I regret to inform that it is not possible to remove water mark from documents which are already processed with free license. You have to again generated documents with full license. You need to apply license file and than generate file.
