Frequently asked questions
What's the difference between EPUB and MOBI?
EPUB is the open, widely-supported ebook standard; MOBI is Amazon's Kindle format. Newer Kindles also accept EPUB, but many older ones need MOBI or AZW3.
Will my formatting carry over?
Yes — the conversion preserves chapters, text and images. Ebooks are designed to reflow, so complex fixed layouts may adjust.
MOBI or AZW3 for Kindle?
AZW3 is newer and richer; MOBI has the widest device support. Try AZW3 on modern Kindles, MOBI for older ones.
Can I convert several books at once?
Yes — add up to 25 files and get a ZIP back.
