FAQ

Frequently Asked Questions

  • Kindle devices don't officially support custom screensavers (they usually show ads or the cover of your current book). However, a common workaround involves tricking the Kindle into displaying a book cover that is actually your desired image:

    1. Use our tool to create your image, ensuring it has the correct dimensions for your Kindle model.
    2. Convert your resized image file (e.g., PNG) into an EPUB file format, making sure the image itself is embedded as the EPUB's cover. You may need to search online for "image to EPUB cover converter" tools or use specific software like Calibre to achieve this.
    3. Send the final EPUB file to your Kindle library using Amazon's Send to Kindle service (via email or the web uploader).
    4. On your Kindle, go to Settings > Device Options and ensure "Display Cover" (or similar wording) is turned ON. This setting shows the current book's cover on the lock screen.
    5. Sync your Kindle to receive the new EPUB file.
    6. Open the new EPUB "book" in your Kindle library (it will look like your image).
    7. Leave this "book" open and put your Kindle to sleep. The lock screen should now display your custom image.

    Note: This is a community workaround, not an official feature. Its effectiveness may vary depending on Kindle model, firmware updates, and the specific tools used for EPUB conversion.

  • Adding custom screensavers to Kobo devices involves connecting it to a computer:

    1. Connect your Kobo to your computer via USB and tap "Connect" on the Kobo screen when prompted.
    2. Open the Kobo drive on your computer (it appears like a USB drive).
    3. Navigate into the .kobo folder. (You might need to enable "Show hidden files" on your computer first).
    4. Inside the .kobo folder, create a new folder named exactly screensaver.
    5. Copy the image file(s) you downloaded from our tool into this new screensaver folder.
    6. Safely eject the Kobo drive from your computer.
    7. On your Kobo device, go to Settings > Energy saving and privacy.
    8. Make sure the options "Show current read" and "Show book covers full screen" are both checked (enabled).
    9. Put your Kobo to sleep, and your custom image should appear!
  • KOReader makes it easy to set up custom screensavers. Follow these steps:

    1. Connect your e-reader device to your computer via USB cable

    3. Create a new folder (e.g., screensaver) to store your images
    4. Copy your desired screensaver images into this folder
    5. Safely eject your device from the computer
    6. On your device, open KOReader and follow these steps:
      • Tap the gear icon (Settings) in the top menu

      • Choose Sleep screen
      • Select Wallpaper

  • This tool allows you to easily resize and position images for your e-reader device. You can select from popular e-readers like Kindle, Kobo, or Remarkable, upload your image, and then adjust it to fit perfectly on your device's screen. The tool maintains the proper aspect ratio and dimensions for each specific device.
  • E-readers have specific screen dimensions and aspect ratios. Using properly sized images ensures they display correctly without stretching, cropping, or unnecessary black borders. This is especially important for cover images, wallpapers, and screensavers.
