How to Remove Drm from PDF, Remove pdf ebooks drm.
Firstly, I seem only to be able to open them in ADE and then when I try to print I am told that I can only print 90 pages (was going to print to pdf).
Normally I wouldn't mind, but when opening on my Sony 505, the text is too small. When I make it bigger, it loses the nice formatting.
I have looked around but found no real answer as to how I may be able to remove the DRM. I have tried a demo of copistar, but this doesn't seem convert to text meaning I couldn't get it to a better format.
So, any advice on how I can get the file to a better format? Being that the 2 books I have bought run into around 600 pages each, I don't want to be doing a load of manual work so anything automated would be great.
Is there a format that I should be buying to make my own life easier? As previously mentioned, I have a sony 505.
I have also bought epub which looks great on my 505 although there are some things I wanted to change but can't due to DRM. I can live with that though.
With the PDF files, it is much harder for me to 'deal' with the problems.
Many thanks in advance.
-----------------------
The DRM of three popular formats (MOBI, LIT, eReader) has been cracked, and Calibre will format shift DRM-free ebooks in any of these formats to ePub (or LRF). Of these, LIT is the closest to ePub and is what I would recommend if you have a Windows PC (MS Reader and Internet Explorer are required to buy LIT ebooks).
-----------------------
With respect, the DRM has not been "cracked" - that would imply the ability to remove DRM without knowing the encryption key, and that hasn't happened.
What has happened with these three formats is that, given a known encryption key (eg the PID for a Mobi file), the action of the legitimate reader for the formats has been "reverse engineered", allowing tools to be written which produce a DRM-free version of the file. The key point is, though, that in order for this to be done, the encryption key has to be known.
