MOBI is dead, EPUB is the standard

For years, the only way to send personal ebooks to Kindle was the MOBI format. People used Calibre or online converters to turn their EPUBs into MOBI before emailing them to their Kindle. In 2022, Amazon quietly added native EPUB support to Send to Kindle. In 2023, they stopped accepting MOBI files entirely. If you're still converting EPUBs to MOBI — you can stop. EPUB is now the only format that makes sense for personal ebooks on Kindle.

Why EPUB is better than MOBI ever was

MOBI was a legacy format with real limitations — poor support for complex layouts, limited CSS styling, and no embedded fonts. EPUB supports modern typography, embedded fonts, and better image handling. Books that looked mediocre as MOBI files often look noticeably better sent as EPUB.

Where people get EPUBs

You might have EPUBs from Humble Bundle book sales, Project Gutenberg's free library, O'Reilly technical books, Smashwords, StoryBundle, or exported from Calibre. Some publishers sell DRM-free EPUBs directly. All of these work with DropKind — upload the file and it goes to your Kindle. And if you have a PDF you'd rather read as reflowable text, DropKind can convert PDFs to EPUB too.

Frequently Asked Questions

What about DRM-protected EPUBs?

DRM-protected EPUBs from other stores (like Kobo or Google Play Books) cannot be sent to Kindle. Only DRM-free EPUBs work. Most indie publishers and bundle sites sell DRM-free.

Can I send EPUBs from Calibre?

Yes. If you manage your library in Calibre, just export as EPUB and upload to DropKind. No need to convert to MOBI or AZW3 anymore — Kindle accepts EPUB natively.

Will my EPUB look the same on Kindle?

Mostly yes. Text, chapters, images, and table of contents carry over. Embedded fonts may or may not render depending on your Kindle model. The reading experience is generally very close to what you see in any other EPUB reader.

What's the file size limit?

DropKind supports EPUB files up to 15 MB.
