Kobo
On stock Kobo software, you can export a PNG or JPEG at your reader’s screen size and place it in the .kobo/screensaver folder. This community method does not require KOReader.
1
Clara HD uses 1072×1448, Libra 2 uses 1264×1680, and Sage uses 1440×1920. Pick your exact Kobo model in the editor before downloading.
2
Download the image, connect your Kobo by USB and tap Connect on the reader. Back up any existing files before changing them.
3
Open the hidden .kobo folder on the Kobo drive and create a folder named screensaver inside it. Drop one PNG or JPEG there for a fixed sleep screen, or several images to rotate. Press Command+Shift+. on macOS or enable Hidden items in Windows File Explorer to see hidden folders.
4
Safely eject the Kobo. In Settings → Energy saving and privacy, turn on Show current read and Show book covers full screen, then put the reader to sleep. Menu names vary slightly by firmware, and full power-off may still show the book cover.
To return to book covers, delete or rename the screensaver folder (for example, screensaver-backup). If your image does not appear, confirm that screensaver sits inside .kobo rather than at the drive root, check that the file is PNG or JPEG, and verify both cover toggles in Settings.
KOReader uses its own sleep-screen settings and ignores the stock Kobo interface. Follow the KOReader guide below to choose a single image or a random folder.
Choose your exact model in the editor to reduce stretching or empty borders. Matching the resolution does not unlock custom lock screens in the device firmware.
