    How can I securely present a PDF on the web?

    hirte7 Community Member

      Hi,

      is there any Adobe tool that would allow me to present a PDF on the web, so that visitors can open and browse through a PDF but can not download or alter the content? I know there are services that convert a PDF into a "browseable" form, but is there any other way with Adobe's own tools?

       

      Thanks.

          Unless you stream the file using expensive DRM technology, in order to view

          a PDF is has to be downloaded, so that part is out of the question.

           

          Restricting modification of a PDF is possible by applying a security policy

          (File - Properties - Security), but there are plenty of PDF viewers out

          there (cough, Apple Preview, cough) that do not respect these policies so

          overcoming such protection is quite easy.

            Even with DRM, there is no concept of streaming in PDF files. The content can be viewed only after it's been downloaded to a local cache.

             

            When a PDF file is "optimized for web view", the order of the content is arranged so that the first pages can be seen before the document has finished downloading; but it's only a matter of time, the file is always sent in its entirety.
