Removing Illustrator editing capabilities from PDF files?
in [Mac Applications]

From: AES on 18 Jun 2010 04:54 Is there a way to remove the Illustrator editing capabilities stored within a PDF file that has been prepared in Illustrator and Saved As PDF with Preserve Illustrator editing capabilities turned on? (other than re-opening the file in Illustrator and re-Saving it) More detail: I like to make 1-page PDF documents (slides) in Illustrator CS; keep master copies with "Preserve Illustrator Editing Capabilities" turned on; then make dupes of selected files (in the Finder) to use when I'm putting together a presentation. A single PDF with a few hundred characters of text and some vector graphics (no jpegs or pixel graphics) may be only 30K in size if saved from Illustrator as PDF with Illy editing capabilities turned off -- but becomes 400K with the Preserve Illy editing capabilities left on. When I try to shrink one of these back down to 30K using PDF Shrink, using the Remove metadata and "Foreign app" options in PDF Shrink, it only shrinks to about 350K. Am I missing something In PDF Shrink (which I otherwise find very useful? Can Graphic Converter do this job?

What actually happens here is that the Illustrator file is saved inside the PDF file. When you reopen it with Illustrator it actually opens the saved file inside the PDF file, it doesn't attempt to interpret the PDF file. So yes, the PDF file gets (a lot) bigger. > When I try to shrink one of these back down to 30K using PDF Shrink, > using the Remove metadata and "Foreign app" options in PDF Shrink, it > only shrinks to about 350K. > > Am I missing something In PDF Shrink (which I otherwise find very > useful? Can Graphic Converter do this job? I don't know of any tools that will do the job. The data is stored in 'application-spcific' sections of the file. Only the relevant application (usually the creator) knows what to do with these, so everything else leaves them alone. Though the 'foreign app' sounds like it ought to do that. Taking a quick peek it look slike PDF Shrink possibly interprets the PDF file and creates a new PDF from it. You could do the same with (for example) Ghostscript. Feed the original PDF as the input, create a new PDF (potentially with custom settings) and it will probably be OK. Its entirely possible to create something which would specifically strip out the Illustrator saved file, but I don't know of anything which does it. Of course, this is all without seeing the file, its possible there is something different about your files. Ken

It is possible that Inkscape (http://www.inkscape.org/) is able to do this. But I have not tried. ///Peter

But I have not tried. I was just thinking about the same thing. And Inkscape has a command line interface that would make it possible to create a simple command to do the thing -- in the case that it works and does not cause any side effects (which I doubt it will).
