View Full Version : edit PDF metadata for free on a Mac?

03-13-2009, 08:40 AM
I have a few PDF files with incorrect author and title metadata that are really screwing up my title and author list on my Sony PRS-505. Does anyone know a free PDF metadata editor for Mac? If not, I can boot into Windows on my Mac, but I'd rather not if I can help it. Thanks!

PDFtk ( can do it, and there's a free mac version available, but it's not exactly the most user-friendly thing in the world, and I've only used the Windows version, personally. Still, it's something.

Perhaps someone else will know of something better.

Just wanted to say that I found the program CombinePDFs ( which fulfills my needs and only costs 20 or $30 which is cheap enough for me. The trial version lets you work on 1000 pages before you have to register. :)

Definitely way too much to pay. You can combine PDFs for free with pdftk as well, not to mention a variety of other things. I'm sure there are other free applications. Can't calibre edit the metadata as well?

I just got stuck onthe same problem - why I found this thread - and even if things look all right in Calibre they aren't on the Reader.

Did you try this?

(That comes from a later discussion on the same issue, in this thread:

If you want to set metadata on many PDFs, you can use LRFTools ( command).
