Convert Kobo Kepub to EPUB and Remove DRM

Posted by on .

About two years ago, when we sync purchased eBooks via Kobo for desktop app, we can get EPUB files, then we can sideload them to Sony eReader or any other device which supports Adobe Adept DRM to read.

Later Kobo changed the rules, we can only get .kepub files from Kobo for desktop app, even the files are saved in a pretty deep path. And no program can read these .kepub files except Kobo. That brings much trouble to us.

I used to write an article about how to get EPUB files from Kobo official site, in the past days this is only method when we want to read Kobo books on apps or devices other than Kobo's. Until now...

Days ago, I found a Calibre plugin, which can directly convert Kobo to EPUB and remove DRM at the same time. You need no to convert acsm to EPUB any more.

Update on 2015/07/13: Epubor Ultimate now also supports directly convert DRM KEPUB to EPUB and works better than Calibre.

Update on 2015/12/23: Epubor Ultimate and Epubor All DRM Removal now supports Kobo 3.19 DRM, which is the only one among all the ebook softwares.

First things first: Before reading the following parts, please make sure you have got Kobo for desktop installed and synced the purchased eBooks.

Method 1 Convert with Calibre Obok DeDRM Plugin

Step 1. Install Calibre and the plugin

Notice: The Calibre plugin doesn't support Kobo desktop 3.19 and Kobo eReader firmware version 3.19, if you are using Kobo version 3.19 and later, please read Method 2.

Go to Calibre's official download page to choose the correct version for your computer's operating system. I am going to use Calibre for Windows 7 as example, but it is also working on Mac and Linux, there won't any operating diffrecence.

This plugin is called Obok DeDRM, please click the button below to download this plugin. (Disclaim: I get this plugin from website, someone in MobileRead forum sent me the link, and the source is reliable, no malware or virus is contained.)

Download Obok DeDRM Plugin

Open Calibre, click "Preferences" --> "Plugins".

As this plugin is not yet collected by Calibre's plugin library, we can only manually install it. Therefore, we need to click "Load plugin from file", and choose the obok_plugin.zip you just downloaded from the blue button above.

Click some "OK" and "Yes", keep all the options default. Finally you need to restart Calibre, and you will see the plugin displayed on the top menu bar.

Step 2. Run Obok DeDRM plugin to convert KEPUB to EPUB

Click "Obok DeDRM" on the menu bar, you will see an image like this.

The plugins finds the synced books automatically and display them in a list. Choose the files you want to process and click "OK".

A small tip: You can choose multiple files by pressing "Ctrl" or "Shift" like what we do in windows file explorer.

convert kepub to epub

While the plugin converts the Kepub files to EPUB, it also removes the DRM. You can find DRM-free EPUB files in Calibre's library folder.

Now you can easily read Kobo books on any app or device supporting EPUB format, and you can also use Calibre to convert it to Mobi and read on Kindle.

Important points to update

If this plugin fails to process your KEPUB files, please delete the Kobo desktop app and re-install it, then try it again.

Obok plugin only displays the DRMed Kobo books, in other words, we can't use this plugin to convert DRM-free Kobo Kepub books to normal EPUB. Some resources said we can manually change the extension name to EPUB, and use Calibre to convert it to EPUB again. However, I personally don't recommend this method, it might output an messed up EPUB file. However, I will follow up this issue, will update the article once there is a solid solution. (Now the following part is the updated method, highly valued by thousands of customers who are crazy eBooks reading lovers.)

Method 2 1-Click to Convert Kobo to ePub

Step 1: Install Epubor Ultimate Converter

I often used method 1 to help me resolve my problems but the result is, I still met lots of another problems. It's painful to get a messed up ePub file! So Epubor team tried best to find a better way than this for a long time. Everything comes to him who waits, now you just need to an Ultimate eBook Converter then anything resolved perfectly.

Step 2: Sync Kobo desktop to get Kepub files

Run the Kobo desktop reading app on your computer, and then log in with your own Kobo account. By default this app will automatically help you sync your Kobo library after you get the started.

I've said that all the files synced via Kobo desktop are with KEPUB format and are saved in a pretty deep path. But where to find them after all? What's the exactly location of Kobo KEPUB files?

For Windows: C:\Users\(user name)\AppData\Local\Kobo\Kobo Desktop Edition\kepub

For Mac: .../Library/Application Support/Kobo/Kobo Desktop Edition/kepub

Step 3: Remove DRM from Kobo KEPUB

Get Ultimate converter started please. It will automatically detect your Kobo desktop including all the synced KEPUB books.

Then grab those KEPUB books to the left area.

Different from using Calibre plugin, with this product when books added, drm soon removed with high speed, while Calibre asks us to load a plugin first and then start removing drm.

Another good point of this tool is, Calibre Obok DeDRM plugin can only deal with DRMed Kepub books. This means, before drm removing we have to check these books had drm or not, and what's worse, for those drm free kepub files, we can't convert them to epub. But if you choose Ultimate converter you won't have these worries! It helps detect all the synced KEPUB files no matter they had drm or not.

This in-depth guide also has explained this feature in detailed.

Step 4: Convert kepub files to epub

Once drm removed, then the following step is pretty simple. From the "Output Format" choose ePub, then click on "Convert" button.

Then the converting will start. Batch conversion supported well, just with one click.

Wait for a minute. Once finished it will pop up a window that tells you where the output ePub books are stored.get converted epub

Anything finished well here. Now you can open and read these converted ePub books with any ePub reader, or transfer your ePub books to iPad for reading with iBooks, and more.

What about this method? Have some better suggestions? Don't forget to leave your kind comments please.

Here we also prepare a guide video to help you finish the job.

I tried this and I got the following error: "No userkeys found to decrypt books with. No point in proceeding." I have tried reinstalling Kobo for desktop but I still get the same error message.

As this plugin is not developed by Epubor, we cannot provide a solution. Sorry about that.

You are a hero! This totally worked for me. THANK YOU!!

Worked like a charm.  Simple, easy, and now I can finally buy ebooks legally AND read them on my Sony Reader.  Loosing the Sony Reader store and getting forced into Kobo was a bummer but this plugin solves my problems.
Thank you!

Très pédagogique bien documenté (en anglais). Je n'arrive pas à convertir un livre reçu sur la liseuse Kobo, dommage.

Amazing, thanks a lot! Just bought a kobo book to read on my Sony PRS-T1 in a region where the kobostore isn't integrated to it yet (and guess it will never be...) and thought I had wasted money. THANKS AGAIN!

Well, I only have a Kobo-reader since two days, and have been reading Kobo ePubs for a long time on other ereaders (BeBook, Boox) and on non-Kobo ereader apps on Android tablets and phone.  I never ever had one kepub...

If you have a non-Kobo ereader, or if you buy books from more stores than only Kobo, why install the Kobo desktop app?
If you buy books from other stores as well, or if your ereader is non-Kobo, just use the direct download links for the ePub files in your Kobo-account. Why having your Kobo-books synced to your desktop via the kobo desktop app, if you can't sync reading position etc. because you don't use a Kobo reader?  And the desktop-app won't allow you to manage your books bought in other stores.

You can read the ePubs downloaded from your Kobo account on every reader authorized with your Adobe ID, or you can first add them to your Apprentice-Alf-enhanced Calibre Library...  (and if you really want, you can even sideload those epubs as kepubs to your Kobo device, if you like the extra features that this format gives you on your Kobo reader...)

I just downloaded the trial version of Ultimate for Mac (version and I can't get it to work with my Kobo e-books. When I drag and drop one of the items from the right column, the app opens an alert dialog with no buttons in it, which can't be dismissed. and I'm stuck there...
