Converting kindle to nook

A quick search produced this as the first result: https://play.google.com/store/apps/details?id=com.daemon.ebookconverter&hl=en&gl=US. Also available on apkpure if you really want to avoid Google.

I also found this online convertor: https://www.onlineconverter.com/android-ebook

I believe that Nook use epub as their format, which is the most widely-used format going, so any convertor should be able to produce that. Provided of course that your Kindle books aren't DRM-locked: if they are then you'll probably have to remove that first, which I'm wary of discussing here because I'm unsure of US law on this (it's legal where I am for personal use, provided you don't redistribute the works afterwards, but as Rob lives in the US I don't want to get him into trouble if US law still forbids it ).

I should note that I've not used either of the things linked above as I do all of my ebook management using Calibre on a computer.

 

yep kindle books have a drm so you will not be able to use it with the nook app.

 

There are indeed things that remove DRM (certainly on computers, I don't know about phones). Where I buy a book that contains DRM (not all do) the first thing I do is remove it, regardless of whether I need to in order to read it on a particular device. And I won't buy an ebook if I can't do that.

 

When you say you need "access to Kindle" does this mean that the books are loaded into the Kindle app on your phone? I don't use that app, but if it doesn't store books in the "kindle" folder in your internal storage (or SD card) that probably means it's storing them as "private" app data (in /data/data/<kindle package name>), which you'd need root to access. And to be honest that's what I would expect Amazon to do, as it keeps more control in their hands.

If these are books you bought from Amazon you can go back to Amazon (with a browser) and download a copy, which you can then de-DRM and convert. The catch is that they may not offer this option if you only have the Kindle app on a device (I actually have a Kindle e-reader, which I sideload books onto from a computer - I keep its WiFi permanently off so that Amazon cannot collect information about how I use it). But in case you do have this option, here's the recipe: log into Amazon from a web browser. Go into your past orders, find one of the books, click "content and devices" and this will give you a list of all books you've downloaded from them. Then for each book the "actions" will include "download and transfer via USB". You may have to do this for each book (tedious), but this will give you the actual ebook files, which you can then de-DRM and convert.
