DRM Issues with Kindle


  • Premium Member

    Hello,

    I have always bought your books on kindle but recently kindle has decided to take away a lot of your books so I decided to buy the EPUB file and send to my kindle. For Potions Volume 1 it was as easy as changing to MOBI and emailing my kindle. But Potions volume 2 is over 25mb and can't be direct emailed. I used dropbox to get around this but every time I try to read the document I get an error that there's DRM on the file. Having books stored as files in documents is already bad but this makes it impossible to read this book on the kindle. I tried Calibre and even some "drm remover" apps since your site says its DRM free anyhow but I can't seem to get volume 2 to work. What can I do?

    None of the books you buy directly from JNC have DRM on them. You can confirm that by opening them in an application like calibre or one of many apps that you can download for free for your phone. Converting the epub file to mobi won't add DRM either (which you can probably verify with many of those same apps, though mobi isn't going to be as widely supported as epub). As such, it makes no sense to do anything to attempt to remove the DRM from the file. There is none.

    Rather, it sounds like the file is probably being corrupted somewhere in the process (like maybe with how you get it on your Kindle; I don't know anything about that process though, since I've never owned a Kindle). But if calibre can read your mobi file, then the file should be fine at that point, and you'll need to figure where in the process after that things are going wrong.

    @goldenargo85 The actual limit on email to Kindle is 50MB, but your email service might impose smaller limits. A binary 50MB file will become a 67MB email; if your email service limits you to 30MB (a lot have a 10MB limit!), 25MB documents are too big.

    Amazon has a utility you can install on Windows or Mac to "send to Kindle", which (supposedly) can deal with that, probably by send the email through Amazon's server, rather than your service.

    Also, calibre can directly drop the book on your Kindle via the USB cable, but you have to convert to AZW3 for that to work. That's how I had to put Bakarina 5 on my Kindle, because it's over 60MB as a MOBI file.

    Yeah the website says no DRM and I haven't had problems with volume 1 but Volume 2 has the DRM message. I think its going wrong when I have to drop box the MOBI file over vs email which I can do under 25mb and it thinks its something its not. I have spent about 4 hours researching different ways to possibly get around this before posting so I'm reaching out "to figure where in the process after that things are going wrong."

    Two (particularly 3) ways how you can make it work. As you mentioned calibre simply convert to mobi or azw3 (I prefer azw3 as I can use my own fonts) plug in your Kindle into it and send it over "the cable". Or start the book server in calibre and go to the IP address mentioned there on your Beta Browser in the Kindle and simply download it this way.

    Second way was already mentioned. There is a program on Amazon with the name "send to kindle" (easier to find with a google search as if going trough the help topics on Amazon). There you can also send your files to the free email address on your kindle. Then it is in the cloud.

    Third (and as it is not so feasible so I did not mention above 3 ways) would be to open an account with an email provide who has not restrictions for email size. Although those are hard to find and mostly only for paid email subscripers.

    And where it could go wrong. Some parts could be the culprit. Clearly the epub files have no DRM. And calibre doesn't add DRM. So the only way where it could go wrong is at the time you send it to dropbox or when you download it from dropbox. If I recall correctly dropbox has a built in epub read so maybe there is the point of error.

    For books over 25MB but smaller than 50MB, you can still email them if you use an email service that allows larger file sizes. I set up a free GMX account just for sending Kindle files, as setting up Calibre to email from Gmail isn’t possible anymore. This gives me the advantage of both being able to email directly from Calibre and being able to email larger books, which JNC books tend to be due to the illustrations.

    Only one I couldn’t do like this was that larger volume of Bakarina as it was over 50MB, and I eventually just put that in iBooks as I read light novels on my iPad usually instead of my Kindle, so it’s easier to zoom in on illustrations. I couldn’t figure out a way to get it into the Kindle app on my iPad directly due to its size, and it doesn’t matter which app it is in if it’s not in the Kindle documents, as sideloaded documents don’t sync between devices.

    @lilitu93 You could always upload it to your Google account. This will allow you to pull it down on any device that can access the Play Books app.

    My method seems to be a little different. I upload my premium ebooks to my Google Drive (I use an email just for my books) and then download them from GD and read them with Moon+ Reader Pro (paid version, 10 or 15 USD?, one time purchase)
    Not certain if the app is available on IOS, my device is a Galaxy S10+.
    An advantage I have noticed is that the developer responds to any posted issues in a days time with help. App also syncs across multiple devices.
    I know other people stand by Calibre but I could not get it to work as nicely as othersseem to. More than likely me missing something but w/e.

    Is Calibre even available on Android, I only know of the Windows version? Likewise, I don't think Moon+ Reader is available on PC outside of forks, so it's really two use cases.

    On Win10 I use the Calibre viewer, on Android Moon+ Reader, and when I'm on the move I just use my Kobo reader to which I transfer ebooks by usb, and the Kobo reader is which gets most use as it's so easy to take with and no risk it runs out of batteries, besides being sturdy and rain-proof.

    Download the epub directly to your Android device and go to open it. It will then offer to upload a cloud copy to Play Books if you try to open it in that app.

    It will end up in an uploaded folder on the Play Books app allowing you to download to any device from your Google Account.

    Afaik this has a higher allowable file size than email to Kindle.
