Can't break DRM for Adobe
I bought a book that was advertised as epub, but it has DRM on it from Adobe, which means I can't convert it to PDF, which means I can't read it and take notes directly on it, which is going to make it much harder to study.
I'm using the latest version of Calibre (just downloaded) on my new MacBook Air (M2 running 12.4). I downloaded and installed Apprentice Alf's plug-in which says it will break the Adobe DRM. And yet...it isn't. How do I get this file to PDF? Are there new plug-ins? |

And if you have the latest Calibre, you'll have to install the latest version of the deDRM plugin, which is not the Alf version. Here: https://github.com/noDRM/DeDRM_tools Last edited by Sirtel; 08-20-2022 at 03:26 PM. |

You might also want to use NoDRM's fork of the DeDRM code since that is supported. Apprentices Alf and Harper have passed the torch. Check NoDRM/DeDRM Tools.
If you downloaded an ePub textbook, it likely has Adobe's hardened DRM. See the attached matrix image. |

To be clear ASCM files are not unpacked, they are fulfilled. The ASCM file contains information that Adobe Digital Editions uses to download the actual book from a server. It does not contain the actual book. The DeASCM plugin replicates the functionality of ADE in this regard.

If you have a decent ereader app or Kobo eink, reading and taking notes on epub is FAR better than PDF. Annotations plugin or Kobo Utilities can read Kobo annotations back.
Also you can edit the config on a Kobo so an extra context menu item is on epubs and then export a plain text file with date, location, highlight and note for each annotation. PDFs are really just for publishing or printing or "book replicas" on a big screen. |
