I think you can probably delete them permanently by running something like the pdf distiller to linearize the PDF after editing with ExifTool. (And all other formats this might apply to) I think a simple warning in the manpage/manual (about some formats not being securely deleted) should do.Īnd maybe a warning output when deleting pdf metadata. Quote from: Phil Harvey on November 18, 2012, 11:43:33 AMĪ notification? Could you be more specific? Therefor I assume that the metadata are not properly being deleted by exiftool but are still readable apart from standart specification. When using notepad++ to manually edit the xml tag that contains the metadata, pdf-xchange reader also does not show the deleted informations. Microsoft Office (Version 2003,2007,2010, and 2013 Preview, also Mac OS version) Programms used to originally create the pdf file:Īdope Destiller (Version 6, 8, and 9.0.0) More Information abaut pdf files I tested this on: Other readers still show no meta data other then the ones exiftool edited (in my case nothing)įor everyone who uses exiftool to clean their documents for privacy reasons, this is a serious bug.Įdit2: exiftool 9.60 (windows-version) also does not show the "hidden" meta data.
I tried this with several pdf files on Windows 7 and on Windows XP.īoth Operating Systems never touched the original files and only saw the pdf files after using exiftool for cleaning.Īfter Installing the pdf-exchange Shell extension, the Windows explorer shows the meta too. Neither exiftool, Adope Reader, Windows Explorer, Evince, Okular, Foxit Reader nor Foca did show any Information (apart from the creation date which was x.x.1970)īut the pdf-xchange viewer shows all of the original data. like author are still readable in several pdf readers. for privacy reasons.Īfter using exiftool -all= (using Ubuntu 12.04) on several pdf files, I tested whether or not the meta-data e.g. Today I discovered a serious bug when it comes to removing meta-data in pdf-files e.g.
