    PDF Versions of Documents and  Adobe Reader Versions

    iLaible

      hello

       

      ist there a overview table, which shows the details and compatibility of PDF File Versions and Adope Reader

       

      of is it easy to say

       

      PDF1.3 need Adobe Reader 4.0 and higher

      PDF1.4              5.0

      PDF1.5              6.0

      PDF1.6              7.0

      PDF1.7              8.0

      ...

       

      thanks for the answer where i could find an overview table

       

      if there is a backward compatibility

       

      reading PDF1.7 with Adobe Reader 5.0

       

      maybe additional table which function are compatible

      and which are not supported or create errors by using old Reader with new Documents.

       

       

      hope you have some answers, thanks

      and best regards

          You cannot reliably read newer versions of pdf with older versions. We cannot provide a table, because it depends upon the features used by the file. For example you can usually take a pdf raster image that is saved in an newer format, with an older version. You'll get an error message, but it usually will open. However, if you use a pdf that uses newer security features, it will NEVER open.
