breaking security on a pdf
« on: October 02, 2007, 04:17:20 PM »
Does anybody know if there is there any way of disabling the security on a pdf so I can edit some images, I don't have the password.

As far as I know you can't.

Pitstop won't let you either.

I guess that's why it's there...but frustrating...I feel you pain.

Erik, posted a tip in this forum "Protected PDF" he has a tip although I have not tried it myself yet.
Else there are a few tools out there that can break the security. Heres a link to what is supposed to be a good on (again I don't have this)

Thanks for the tips, I knew I'd read on the forums somewhere, I'd assumed it was the Adobe one (which you can't search on at the moment) so missed what was under my nose here on this forum.

Anyway Erik's Colorsync tip just gave me a blank pages (v4.5.5).
PDFKey Pro; I demo'd it worked fine for page1 so I guess I need to go back to the customer and get them to pay for the full version.

There's also PDF Recover which I have found works far better. PDFKey tended to crash on me. You can get PDF Recover here: http://shop.pdf-office.com/product_info.php?products_id=36

But, it too is non-functional for more than one page, unless of course you pay for it.

BTW, the tip I had suggested seems to work only in Panther. Chardonnay had issues with this as well but the OS in this case was Tiger.

Just tried with Colorsync v4.2 running on OSX10.3.9 still getting just blank pages. the pdf file size drops from 56MB to 68k too so blank pages sounds about right. I'll try OSX10.2 as soon as I can and get back.

Well, it might also be an Acrobat version thing. Chardonnay seemed to think so. I have Acrobat 6 Professional and the one time I tried this I had no problem. I had a 300 page Annual Report as a protected PDF and I got all 300 pages unlocked.

I don't know why the tip works for me, but seemingly not for anyone else....
