Suddenly Can't Remove DRM from Adobe PDF

Siavahda · 12-28-2023, 12:08 PM

I've used Apprentice Alf's dedrm plugin to remove DRM from adobe epub and pdfs hundreds of times. But today, it's not working on a new PDF file.

I'm using Calibre 7.2, DeDRM 7.2.1 by Apprentice Alf et al, Adobe Digital Editions 2.0.1.

The PDF comes into Calibre, but it can't be opened, read, or converted.

I tried installing the ACSM input plugin from here, but it seems to have made no difference - importing the acsm file still results in a pdf I can't open.

I've no idea why it's suddenly not working - nothing has been updated or changed, and this file is from the same place I always get my files, so it's not an issue of getting my files from some new source.

Help?

dedrm has been replaced by nodrm, switch to that.

You need the newest deDRM, which is 10.0.3.
Here:

I had no idea, thank you!

Apologies if I'm being an idiot, but I couldn't find DeDRM_plugin.zip in 10.0.3.

But I found the zip file in DeDRM tools 10.0.9 here. Ran my pdf through it and it's perfect. Thank you so much, I had no idea dedrm had become nodrm!

epubor is copy repackaged of noDRM.

The correct download is on right edge just under Releases on the link Sirtel gave

Yep, was pretty sure that was the case

Oh, thanks! I've always struggled with github. Feel like such an idiot

I now have the proper 10.0.3!
