After purchasing eBooks on Kobo books store, you may want to share them with your wife, friends, or read them on your other devices. But you can't share them because the purchased books are protected by Adobe DRM. It feels like the books is Kobo Vox Reader's but not yours.
Following this guide, you can really own the books you purchased and share the books with anybody and read them on any eReader, even print the pages out if you like.
As default, you have two ways to get Kobo books to your computer: Sync to computer via Kobo desktop software, or download ACSM file from Kobo website, then use Adobe Digital Editions to convert ACSM to EPUB.
But when you sync Kobo books via Kobo desktop software, you can only get fragile files saved in KEPUB folder, not a complete EPUB file. Therefore, if we want to remove Kobo DRM, we have to download ACSM file from Kobo website, then handle it with Adobe Digital Editions and Adobe DRM Removal.
Update on 2015/04/16: Kobo changed their content sync policy, now you cannot get an EPUB file from Kindle desktop (PC/Mac). We update the article to react with the new policy. The guide below is guaranteed to work.
Remove DRM from Kobo eBooks
1. Download .acsm files from Kobo website
Visit your Kobo library, where you can see all the purchased books. On the right side of the cover, there are "Download EPUB" and "ADOBE DRM EPUB" buttons. "Download EPUB" button indicates this book is DRM-Free, while "Adobe DRM EPUB" indicates the book is encrypted.
Clicking "ADOBE DRM EPUB" button you can download an .acsm file, which is the key to get a complete EPUB book.
2. Install ADE and convert acsm to EPUB
Install Adobe Digital Editions (ADE), and authorize your copy.
Drag the .acsm file into ADE, and you will see the EPUB book is being downloaded.
After the book is fulfilled, the EPUB file will be saved in "Documents/My Digital Editions", and you can remove DRM from this EPUB file.
3. Install Adobe ePub&PDF DRM Removal.
The software automatically scans your Adobe Digital Edition's content folder and imports all the books if you want. And all the imported books will be immediately decrypted. You can also manually drag the EPUB file into Adobe DRM Removal's main interface.
When the process has been finished, you can right click on an item and choose "Explore output folder", where saves the DRM-free books.
Before decryption, please make sure you can read them in Adobe Digital Editions, which is very important for your successful decryption.
