Send books to the Kobo Sage with Calibre
Add EPUB books to Calibre and copy them to the Sage over USB, with an optional step for sending them as Kobo's KEPUB format.
This is the direct way to get your own EPUB books onto the Sage. Calibre keeps the master copy of each book on your computer; sending to the device makes a copy there. Deleting a book from the Kobo later does not remove it from Calibre. The process is identical to the other Kobo models.
Before you begin
-
Install Calibre on your computer if you have not already
Calibre is free and runs on Windows, macOS and Linux. Download it from calibre-ebook.com and open it once so it creates its library folder.
-
Add your books to Calibre
Drag your EPUB files into the Calibre window, or use "Add books". Calibre reads the title and author from each file and can download covers and descriptions from "Edit metadata".
-
Connect the Sage with the USB-C cable
On the Kobo, choose "Connect" when it asks. After a few seconds Calibre recognises the device and a "Device" button appears in its toolbar. If it does not appear, the cable may be charge-only — try a different one.
-
Optional: set Calibre to send books as KEPUB
KEPUB adds better page numbers and reading statistics on Kobo hardware. To turn it on, open Preferences, then Plugins, expand "Device Interface plugins", double-click "KoboTouch", and enable the option to convert EPUB to KEPUB when sending. Plain EPUB works without this step.
-
Select the books and send them to the device
Highlight one or more books, then click "Send to device" (or right-click and choose "Send to device", then "Send to main memory"). Calibre shows a "Jobs" counter in the bottom-right while it works. Wait for that to finish.
-
Find the books on the Sage
Unplug the device. On the Kobo home screen, open "My Books". Sideloaded books appear alongside anything from the Kobo store, sorted by most recent.
