Is it possible to find "non-image objects compression" using preflight in "Acrobat X pro"?
Thanks in advance for your support.
If you're talking about document structure compression (using Flate) then it's a native part of the PDF standard and will be applied to all files by default. It can be removed with Preflight but unless you're editing the COS stream there's no reason to. All current PDF reading applications support compression in PDFs.
