I'm using Acrobat Professional 6.0 to reduce large files. Some of the files were produced using Acrobat Standard 8.x, but saved to be compatible down to version 4.0. When I open these, the Reduce File Size option is greyed out, as is the PDF Optimizer. I tried doing a Save As to see if the versions mattered, but the new file still had the features disabled. I checked Security, but the files are wide open for changes. This happens on both large and small files. The writer who created the PDF has the feature enabled on Acrobat Standard 8 on these same files, so I think it must be a version issue.
I have not noticed this issue before, but then this is the first time we've done size reduction for a full release. Whast's the cause, and is there a fix using my 6.0?
Thanks!
The reason you can't reduce the file size is that the lowest [oldest] version supported is acrobat 4. In that earlier version, there weren't the same capabilities to reduce and compact the files' contents as in later versions, so there's nothing that the Reduce File Size or PDF Optimizer can offer.
