Common questions

›How do I set a custom screensaver on a Kobo?

Connect the Kobo by USB, show hidden files, create a folder named screensaver inside .kobo, and copy your images in. Then go to Settings → Energy saving and privacy and turn on Show current read and Show book covers full screen. Firmware 4.13 or later is required.

›What size should a Kobo screensaver be?

Clara (HD, 2E, BW, Colour) is 1072×1448. Libra 2 and Libra Colour are 1264×1680. Sage and Forma are 1440×1920. Elipsa 2E and Aura ONE are 1404×1872. Nia is 758×1024.

›Why doesn't my screensaver show?

Check the folder is named exactly screensaver (lowercase, singular) inside .kobo, that both settings are on, and that a book is open. With no book open, Kobo shows its default sleep screen.

›Can I use several images?

Yes. Put as many as you like in the folder and Kobo picks one at random each time it sleeps.

›Is it free?

Yes. Kobo files are free, with no watermark, and your photo never leaves your browser.
