I have a PDF document that I want to compress only the image with an «image attribute : filters = JPEG« and not touching the «image attribute : filters = zlib/deflate». The PDF come from InDesign. The resulting JPEG in the PDF come from either PSD. TIF or JPG, but the image with zlib/deflate filters are PNG file. I tried to create a Preflight profil/fix to reduce the resolution, but even if I add an option to only do it on a specific compression filter, all the images are downsampled. I’m lost... Can this be done using a preflight profile or else? Thanks!
