About MOBI
MOBI is the e-book format older Kindles used. Amazon stopped accepting MOBI through Send to Kindle in 2022 in favour of EPUB, so it is now mostly found in old libraries.
MOBI is no longer accepted by Send to Kindle and is not opened by other e-readers. MOBI works on older Kindle devices.
