I'm not convinced about compressing pdf: sometimes it works but many times the result is very close to original (if not bigger). Embedded text in "recent" pdf is already compressed and tools to compress pdf act on embedded pictures (loss of quality). More generally, this is valuable with any compressed file (jpg, png, odt, ods, docx, xslx…) -- Arnaud de Montard ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
