Many tools do not fully remove metadata, but just remove the link with in the metadata table. The data are thus still available in the PDF file itself.
While a lot of people rely on Exiftool to remove metadata, it actually does the same in PDFs. If you remove metadata with exiftool -all= some.pdf
, you can always restore the data with exiftool -pdf-update:all= some.pdf
.
There are several options to remove PDF metadata safely:
- Remove metadata with exiftool :
exiftool -all= some.pdf
- Then remove ununsed objects with qpdf :
qpdf --linearize some.pdf - > some.cleaned.pdf
UPDATE: This page has now been moved to / incorporated into the JET Encoding Guide, in the hope that that that page can slowly grow into a more comprehensive encoding guide.
So this is supposed to be a list of encoding-related resources together with some very basic instructions. Kind of an encoding analogue to fansub.html. This is not a full guide on encoding.
Since this page is starting to get linked elsewhere, I should also make clear that it mostly comes from (a person adjacent to) the JET community. In particular, it's written primarily from the perspective of anime encoding. Still, most parts will hold up equally well for live action and other areas.
This guide may seem fairly technical. Partly this is because I have a background in pure mathematics and this is how I learned the material, but partly it's just because encoding is cursed and co
