Your Kobo doesn't have to wake up to a boring "Sleeping" screen. In less than five minutes, you can display any image you want — stunning book art, photography, hand-lettered quotes, or seasonal illustrations — every single time your device goes to sleep.
The best part? No jailbreaking. No hacking. No voided warranty. It's a feature Kobo quietly built into the firmware, and most owners never find it.
This guide covers everything: the exact folder structure, the correct image sizes for every Kobo model, the two settings you must toggle, and how to keep your screensavers looking crisp on an e-ink display.

1. Does This Work on My Kobo?
Yes — if your Kobo is running firmware 4.13 or later, you can use custom screensavers. That firmware released in early 2019, so any Kobo purchased in the last several years qualifies. This includes:
- Kobo Clara (all versions: Clara HD, Clara 2E, Clara BW, Clara Colour)
- Kobo Libra (Libra H2O, Libra 2, Libra Colour)
- Kobo Sage
- Kobo Forma
- Kobo Elipsa and Elipsa 2E
- Kobo Aura ONE
- Kobo Nia
To check your firmware version: Go to Settings → About Kobo → Firmware version.
If you're below 4.13, connect to Wi-Fi and update first. It's free and takes a couple of minutes.
2. Find the Right Image Size for Your Kobo
This is the most important step most guides skip. If your image doesn't match your screen's exact pixel dimensions, the Kobo will stretch or squish it — and the result looks blurry and amateurish.
Use the table below to find your model's native resolution before downloading or creating any image.
| Kobo Model | Screen Size | Resolution (W × H) | Display Tech |
|---|---|---|---|
| Kobo Elipsa 2E | 10.3" | 1404 × 1872 | E Ink Carta 1200 |
| Kobo Sage | 8.0" | 1440 × 1920 | E Ink Carta 1200 |
| Kobo Forma | 8.0" | 1440 × 1920 | E Ink Mobius |
| Kobo Aura ONE | 7.8" | 1404 × 1872 | E Ink Carta |
| Kobo Libra Colour | 7.0" | 1264 × 1680 | E Ink Kaleido 3 (color) |
| Kobo Libra 2 | 7.0" | 1264 × 1680 | E Ink Carta 1200 |
| Kobo Clara Colour | 6.0" | 1072 × 1448 | E Ink Kaleido 3 (color) |
| Kobo Clara BW | 6.0" | 1072 × 1448 | E Ink Carta 1300 |
| Kobo Clara 2E | 6.0" | 1072 × 1448 | E Ink Carta 1200 |
| Kobo Clara HD | 6.0" | 1072 × 1448 | E Ink Carta |
| Kobo Nia | 6.0" | 758 × 1024 | E Ink Carta |

A note on color Kobos (Libra Colour & Clara Colour)
The Kaleido 3 screen is capable of displaying 4,096 colors, which means you can use vibrant, colorful artwork as your screensaver. However, the color filter layer makes the screen slightly darker than a standard e-ink display. When choosing color images, pick ones with high contrast and slightly boosted saturation — they'll look far better in practice.
3. Step-by-Step: How to Install Custom Screensavers
This method works on all modern Kobo devices without any third-party software. It takes about three minutes.
What you'll need
- Your Kobo e-reader
- A USB cable
- A computer (Windows or Mac)
- Image files in JPEG or PNG format, sized to your device's resolution
Step 1 — Connect your Kobo via USB
Plug your Kobo into your computer using its USB cable. When prompted on the screen, tap Connect. The device will appear as a drive named KOBOeReader.
Step 2 — Reveal the hidden .kobo folder
The system folder is hidden by default. Here's how to see it:
On Windows:
Open File Explorer, click the View tab, and check the Hidden items checkbox. The .kobo folder will appear on the KOBOeReader drive.
On Mac:
Open the KOBOeReader drive in Finder, then press Command + Shift + Period ( . ) to toggle hidden files on. The .kobo folder will appear.
Step 3 — Create the screensaver folder
Inside the .kobo directory, create a new folder named exactly:
screensaver
This is case-sensitive and must be spelled exactly right. The Kobo firmware looks for this specific folder name. Common mistakes that will break it:
Screensaver← wrong (capital S)Screensavers← wrong (plural)screen saver← wrong (space)
Step 4 — Add your images
Copy your JPEG or PNG wallpapers into the screensaver folder. A few things to know:
- One image: The device will show it every time it sleeps.
- Multiple images: The device randomly cycles through them on each sleep event.
- The more images you add, the more variety you get — most users keep 5–15 wallpapers loaded at any time.
Your folder path should look like this:
KOBOeReader/
└── .kobo/
└── screensaver/
├── wallpaper-01.jpg
├── wallpaper-02.jpg
└── wallpaper-03.png
Step 5 — Safely eject before unplugging
This step matters more than people realize. Kobo uses an SQLite database to track every file on the device. Yanking the cable while it's indexing can corrupt the database and leave your device stuck on a "Processing" screen.
Always use Safely Remove Hardware (Windows) or Eject (Mac) before pulling the USB cable.
4. The Two Settings You Must Enable
Installing the images is only half the job. You also need to flip two switches inside the Kobo settings menu, or the screensaver folder will be ignored.
On your Kobo, go to:
Settings → Energy saving and privacy
Enable both of these options:
- Show current read — This tells the device to display an image (rather than text) during sleep.
- Show book covers full screen — This ensures your wallpaper fills the entire screen edge to edge.
With both enabled, the firmware looks for your current book's cover when it goes to sleep — but the presence of the screensaver folder intercepts that request and serves your custom image instead.
⚠️ Important: This method requires an active book to be open. If you're on the home screen with no book open, the device will fall back to the default sleeping screen. Open any book, read one page, and then put it to sleep — your screensaver will appear.
5. How to Optimize Images for E-Ink Displays
E-ink screens are fundamentally different from phone or laptop displays. They don't emit light — they reflect it, using tiny physical capsules of black and white particles. Understanding this will help you choose images that look stunning rather than muddy.
Match the resolution exactly
As covered in the table above, always crop your image to your device's exact pixel resolution before adding it. Real-time scaling on the Kobo's processor is slow and low-quality. Pre-sized images appear instantly and look sharp.
Boost contrast for black-and-white Kobos
Standard e-ink panels support 16 levels of gray. When a color image gets converted, mid-tones tend to compress into similar gray values and the result looks flat and washed out. The fix: before transferring, convert your image to grayscale and increase the contrast. In any photo editor, boosting contrast by 15–25% before converting to grayscale makes a dramatic difference.
For color Kobos: boost saturation slightly
The Kaleido 3 filter layer absorbs some light, making colors appear slightly duller than on your monitor. Compensate by increasing saturation and brightness by around 10–15% before saving. The image will look slightly oversaturated on your screen — and perfectly vibrant on the e-reader.
Stick to JPEG or PNG
While Kobo claims to support BMP and TIFF, JPEG and PNG are by far the most reliable formats for the screensaver feature. Use JPEG for photos (smaller file size, no visible difference), PNG for illustrations with flat colors or text.
6. Advanced: Real-Time Screensaver Toggle with NickelMenu
The native folder method has one limitation: to switch back to showing your actual book covers, you need to connect to a computer and rename the folder. For most people, that's fine. But if you want to toggle between custom screensavers and book covers directly on the device, NickelMenu is the solution.
NickelMenu is a popular community modification that adds a customizable menu to the Kobo interface. It works by executing shell commands from a configuration file, and it requires no technical background to set up — just a text editor.
The toggle works by renaming the screensaver folder to screensaver_old. Because the firmware looks for the folder by exact name, renaming it effectively hides your custom images and falls back to book covers. Rename it back, and your wallpapers return.
This is a more involved setup — visit the MobileRead Forums for the full NickelMenu installation guide.
7. Troubleshooting: Why Your Screensaver Isn't Showing
The screensaver folder isn't working at all
Double-check the folder name. It must be screensaver — all lowercase, no spaces, no 's' at the end — inside the .kobo directory. Also confirm both firmware settings are enabled (see Section 4).
The screensaver appeared, then disappeared This happens when you finish a book and return to the home screen. The firmware only activates the screensaver replacement when a book is actively open. Open a book and the wallpaper will return.
Images look blurry or stretched Your image dimensions don't match your screen resolution. Check the table in Section 2 and resize your images to the exact pixel dimensions for your model.
Images look washed out or flat This is the e-ink contrast issue. Re-process your images with higher contrast before transfer (see Section 5).
Device is stuck on "Processing" after adding images The database may have been corrupted during a non-safe ejection. In most cases, the device will recover on its own after 1–2 minutes. If it doesn't, hold the power button for 10–15 seconds to force restart.
8. Frequently Asked Questions
Will this drain my Kobo's battery? No. E-ink only consumes power when the image changes. Once your screensaver is displayed, it uses zero battery to stay on the screen — even for days or weeks.
Can I use color images on a black-and-white Kobo? Yes. The firmware automatically converts them to grayscale. For better results, do the conversion yourself with increased contrast before transferring the file.
Does the folder name need to be singular — "screensaver" not "screensavers"?
Yes, exactly. The firmware is programmed to look for screensaver (singular, lowercase). Any other variation will be ignored.
How many images can I put in the folder? There's no hard limit. The device can handle dozens of images. Each time it goes to sleep, it picks one at random from whatever's in the folder.
Will this void my warranty? No. You're only adding files to the device's storage — the same way you'd add an e-book. Nothing in the firmware is modified.
How do I go back to showing book covers?
Connect to your computer, and either delete the screensaver folder or rename it to anything else (e.g., screensaver_off). The device will immediately fall back to displaying book covers.
Does this work on Kindle? Unfortunately no — Kindle's firmware is fully closed and does not support this method. Kobo's relative openness is one of the reasons so many enthusiast readers prefer it.
