How to delete pdf mata data by one-time deletion?

Post by celk2010 »

Hi, each time when I want to delete pdf information,
I can only open "document properties"
then delete title,author, subject, keywords one by one
Will there be any ways to delete pdf mata data by one-time deletion?
Or not by pdf-xchange viewer, by other VBS or Excel VBA or other softwares?
Thank you!

Hello celk2010,

You can go to File -> Save as Optimized, and there in the optimization preferences window select to remove all the metadata at once:

Another option would be to "Sanitize" the document:

Hi, Stefan,
Lately I have installed pdf x-change editor latest version
and a new icon appeared in desktop, named "PDF Tools"
In the "Avdvanced" item, one function called "Changing document properties"
it seems can be used to delete pdf document properties
some pdf files succeed, but some failed and showed "operation not permitted for document"
Which reason will lead to the failure?
Thank you!

Hello celk2010,

Those files are either password protected, digitally signed or have XFA forms in them. In those cases not all operations will be allowed - including changing the metadata.

Kind regards,
Stefan

Hello, Stefan,
Foxit pdf editor can remove the metadata by "Ctrl+D" even though it was digitally signed or XFA forms
but only one pdf each time

I'm sure it was not password protected
How to remove the digitally signed or XFA forms?
I want to remove multiple pdf files metadata at the same time
Thank you!

Hello celk2010,

We do not allow any modifications to XFA files - as this could cause unexpected changes to them, so there's no way with our products to do the same with XFA containing files.

Kind regards,
Stefan

Hello, Stefan,
I got your idea, how about those digitally signed pdf files?
Could this kind be modified?
Thank you!

Hello celk2010,

XFA and Digitally signed files are both with restrictions on them I am afraid, so no - you can't remove the metadata from signed files either at the moment.

Kind regards,
Stefan
