KINDLE COMPATIBILITY
Does Your Kindle Support Custom Lock Screens?
CoverLock builds a correctly sized file for your Kindle. Whether your specific Kindle can display it as a lock screen depends on a separate Amazon feature. Here’s what we know, and what’s still unverified.
Make a Kindle Lock ScreenHow the lock screen trick works
Kindle doesn’t have a normal custom-wallpaper setting. CoverLock works around that by building a tiny ebook with your image as its cover. On Kindles where Amazon’s Show Covers on Lock Screen feature is available and turned on, the device shows the cover of whichever book you opened most recently, including the file CoverLock made for you, whenever it sleeps.
So compatibility really comes down to your specific Kindle: current firmware, the Amazon feature present, and switched on.
What we’ve actually verified
We’ve physically tested the CoverLock workflow end to end. A CoverLock-generated file was accepted by Amazon’s Send to Kindle service, appeared in a Kindle library, downloaded to a physical device, opened successfully, and displayed the supplied image as its cover.
What we haven’t yet verified is final lock-screen display behavior across every Kindle model and firmware version. The table below reflects that honestly: screen specifications are solid, but lock-screen cover support is marked as needing verification until we’ve confirmed it model by model.
Compatibility by device
These are the Kindle profiles CoverLock currently sizes images for, pulled directly from our device data so the numbers stay consistent everywhere on the site.
| Model | Generation | Screen | Resolution | Display | Lock-screen cover | Min. firmware | Notes |

| Kindle Colorsoft | Not specified | 7" | 1264 × 1680 300 ppi | Color e-ink | Needs verification | Needs verification | Covers export at the full 1264×1680 black-and-white panel resolution. 632×840/150ppi is the effective color rendering figure, not the export size. |
What to check on your own Kindle
- Look for Show Covers on Lock Screen in your Kindle’s settings. Not every model or firmware version has it.
- Keep your Kindle’s software up to date. Older firmware is less likely to support the feature.
- Check whether your Kindle shows Special Offers ads. Ad-supported devices may show an ad on the lock screen instead of a book cover, regardless of what file you send.
Questions about compatibility
What does “needs verification” mean in the table above?
It means we haven’t confirmed that behavior on physical hardware yet. We’ve verified that CoverLock’s file is accepted by Amazon and opens correctly on a Kindle, but not final lock-screen display on every model.
My Kindle isn’t in the table. Is it unsupported?
Not necessarily. CoverLock builds files at the resolutions listed above. If your device shares one of those screen sizes, the generator will still create a correctly sized file for it.
