The Kindle app keeps downloaded books on your phone for offline reading, and graphic novels, textbooks, and large illustrated titles can each run hundreds of megabytes. You can remove those downloads on iPhone and Android without losing the books, because they stay in your Amazon library to redownload anytime.
Short answer:
- In the Kindle app, long-press a book and choose Remove from Device to delete the download but keep the book.
- The title stays in your Library in the cloud and can be redownloaded with one tap.
- For app cache, on Android use Settings > Apps > Kindle > Storage > Clear cache; on iPhone, offload and reinstall.
Why Kindle Uses More Storage Than You'd Expect
A plain novel is tiny, but the Kindle app also stores illustrated books, comics, manga, textbooks, and PDFs you've sent to your library. Those can be 100MB to over 1GB each, and they pile up if you download generously.
On iPhone, check Settings > General > iPhone Storage > Kindle; the books sit under Documents & Data. On Android, look under Settings > Apps > Kindle > Storage.
The reassuring part: every book you've bought or borrowed lives permanently in your Amazon Library. Removing a download deletes only the local copy, never the book itself.
Remove Downloaded Books (Keep Them in Your Library)
The fastest cleanup is removing downloads for books you've finished. They stay in your library, marked for re-download.
- Open the Kindle app and go to the Library tab.
- Long-press a book cover (or tap the three-dot menu).
- Choose Remove from Device (not Remove from Library).
The downloaded file is deleted, but the cover stays visible with a download icon, ready to fetch again. Target the biggest items first: comics, manga, and image-heavy textbooks free far more space than novels.
Remove from Device vs Remove from Library
The wording on the menu matters, so it's worth pausing on the difference.
- Remove from Device: deletes only the local download. Safe. The book stays in your library to redownload.
- Remove from Library / Delete: removes the book from your Amazon account entirely (for borrowed or sample titles), which you may not want.
For storage cleanup you almost always want Remove from Device. Reserve removing from library for samples and borrowed titles you've truly finished with.
Clear the Kindle App Cache
Kindle also stores cover art, fonts, dictionaries, and temporary data as cache, separate from your downloaded books.
- Android: go to Settings > Apps > Kindle > Storage and tap Clear cache to remove temporary files safely. Avoid Clear storage, which signs you out and removes settings.
- iPhone: there's no in-app cache button, so to reset cache you offload Kindle (iPhone Storage > Kindle > Offload App) or delete and reinstall it.
Keep the distinction clear: a safe cache clear removes temporary files, while clearing the app's data or deleting it removes your downloaded books until you redownload them. See our Android cache clearing guide for the safe path.
Reinstall Kindle for a Full Reset
If storage is still high after removing downloads and clearing cache, a reinstall wipes all leftover local files. Go to iPhone Storage > Kindle (iOS) or uninstall from the app drawer (Android), then reinstall and sign in.
Your full Library reappears after login because it lives in your Amazon account. You'll redownload only the specific books you want offline, leaving the rest in the cloud. This clears orphaned cache and partial downloads in one step.
Keep Kindle and Your Phone Lean
A light routine keeps Kindle's footprint small:
- Use Remove from Device on finished books, prioritizing comics and textbooks.
- Clear the Kindle cache occasionally on Android, or offload on iPhone.
- Avoid mass-downloading your whole library when you only read a few books at a time.
Kindle is one category among many, and the rest of your phone usually needs attention too. A review-first cleaner, Clenoir on iOS or Cleanor on Android, scans on-device and surfaces your largest files and duplicate photos before you confirm any deletion. For a fuller plan, see the clean up phone storage hub and the storage cleanup FAQ. With downloads trimmed, the Kindle app keeps working as before while every book stays safe in your library.
Want the fast version? Cleanor for iPhone scans on-device — nothing uploaded — and surfaces your largest videos, duplicate photos, and heavy caches in one pass. For the full routine, see the free up phone storage guide.
FAQ
How do I remove a downloaded Kindle book without deleting it from my account?
Open the Kindle app's Library tab, long-press a book cover (or tap the three-dot menu), and choose Remove from Device, not Remove from Library. The download is deleted but the cover stays visible with a download icon to fetch again.
What is the difference between Remove from Device and Remove from Library in Kindle?
Remove from Device deletes only the local download while the book stays in your library to redownload. Remove from Library or Delete removes the book from your Amazon account entirely, which matters for borrowed or sample titles.
Which Kindle downloads should I remove first to free the most space?
Target the biggest items first: comics, manga, and image-heavy textbooks free far more space than plain novels, since illustrated titles and PDFs can be 100MB to over 1GB each while a plain novel is tiny.
