Conversion of mbp1 files to mobi file format

It is not possible to convert .mbp1 files to .mobi files due to the fact that .mbp1 file contains only annotations for a digital book and not the actual ebook. If you really need to convert Kindle book to MOBI, you will have to find AZW3, AZW etc. ebooks that actually contain the content (the text) which can be converted, mbp1 to mobi conversion is not doabe. Ebooks and publicarions that are DRM protected are typically impossible to convert unless you somehow circumvent the protection.
