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 the unique method when we want to read Kobo books on apps or devices other than Kobo's. Until now...
- Obok plugin method: Convert KEPUB to ePub with Calibre?-- If you are always using Calibre to manage files.
- Easy method: Convert KEPUB to ePub and remove drm with Ultimate Converter?-- Just with 1 click to convert and remove drm.
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
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 v6.5.4
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 "Yes" and "OK", 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 plugin 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.
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:.../Users/(user name)/Library/Application Support/Kobo/Kobo Desktop Edition/kepub

Q: I cannot find the kepub files on my mac. There is no kobo folder under Application support. Why?
Maybe your Kobo desktop is not downloaded from kobo official site, but from App store. Please ensure that your kobo for mac is from official site. This is the most important for kepub drm removing.
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 right 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. Select EPUB as output format, 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.
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.

Thank you!
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...)
super Thanks !!
Sorry,
i haved tried and tried, ut i cant do it like this way, when i want to read it, i see strange sings andnot the letters from the book.
Whats i done wrong?
How can you transform your kobo ebook, when you can only download it on your smartphone and not on the kobo desktop?
Thanks a lot.
Digging in the smartphone, I could find the books apparently uncompressed. Instead of a single file, the book is a folder structure.
Any ideas of what to do with this? I already attempted to zip the file structure and change extension file to .epub. When Epubor tryes to open it, it displays an error message.
We are sincerely sorry for this issue. You may download the Epubor Ultimate to have a free trial. It will strip the DRM from the Kepub successfully.
Not working :(

I cannot find the kepub files on my mac. There is no ../Library/Application Support/Kobo/Kobo Desktop Edition/kepub, Kobo is not listed under Application Support at all. Help?
Everything works great, exactly as described here; including removing and reinstalling KOBO, in case a book does not get decrypted.
Thank you!
Can you please make an edit to reflect that? Thanx!
Have a nice day.
Can you please send us the decrypted books and point out the issues with the screenshot? Then we will try our best to help you resolve it ASAP.
