I found that we can edit a pdf file which is uploaded in document library using
Adobe Document Cloud and SharePoint Online.
So is there a way to edit a pdf file from a document library in the browser using
SharePoint 2016/2019 server? Any free product or a product which can be bought in order to do it? I tried with TextControl and Aspose.PDF , but couldn't make it work, do not know if the problem is in my environment or they are not just working with SharePoint.
