How to sign a pdf file and save it directly back to sharepoint site?


  • Hello,

    I own a Sharepoint site for testing. It is installed in my computer with Sharepoint 2010 (WSS). What I want to do is to find a way to achieve a signing function for pdf file type on sharepoint.

    By refer to this site below, the site has been able to recognize pdf file type and open it and edit it directly on the sharepoint site.

    I can edit the pdf file by checking out and then the modification will be save directly back to the pdf file in the shared document library when I am done. Now the problem is, I cannot save the pdf directly back to sharepoint after I inserted a digital signature to the pdf file.

    Everytime I inserted a digital signature to the pdf file, a "save as..." window would pop up and asked me to save the signed pdf file as another file in my local computer, so the changes were not applied to the original pdf file on the shared document library of my sharepoint site. I have to upload the local signed version back to the site and replace the old one manually.

    Any suggestion? Thank you.

    According to my analysis, for Digital Signatures: Adobe has changed the behavior around digital signatures and SharePoint-hosted PDF files. Now, when digitally signing a SharePoint-hosted PDF file, it will be saved directly to SharePoint if that PDF file is already checked out. If not, the user will be prompted to check it out. When digitally signing a SharePoint-hosted PDF file in Acrobat X, Version 10.0, the user would be prompted to save that file locally and would then need to upload it separately to SharePoint as a new version.

    I suggest that you use Acrobat X, then check the result. For more information about Acrobat X, please refer to

    In addition, you can also consider the following third-party tool:
