How to convert .lcpa to mp3 audiobook?-Try Epubor Conversion Service
Can I convert the LCPA to MP3 format to make it compatible with my favorite MP3 player? As explained above, LCPA files can only be accessed with a restricted eReader. In contrast, MP3 is a widely used and universally supported audiobook format, compatible with almost all audio players. It's easy to understand why audiobook enthusiasts might want to convert Readium audio to MP3 format.
Is there any tool that can help with this LCPA-to-MP3 conversion? Unfortunately, I don’t think so. I know the Calibre DeDRM plugin can handle some older versions of Readium LCP books, but it doesn’t support LCPA audiobooks.
