Download and read
Your MOBI downloads straight to your device and the copy on our server is deleted the moment the transfer starts.
Why convert EPUB to MOBI
A Kindle Keyboard, an early Paperwhite or a legacy reading app will happily open MOBI and quietly ignore an EPUB. Converting is the difference between a book you can read tonight and a file sitting unopened on the device.
MOBI understands a smaller slice of CSS than EPUB, so elaborate layouts are simplified on the way across. Paragraphs, headings, italics, lists, images, the cover and the author metadata all survive, which is everything a novel needs.

| Images | Scale with the text around them | Simplified and often downscaled |
| Best for | Novels, textbooks, long reads | Older Kindles and legacy apps |
EPUB to MOBI questions
Is MOBI still worth using?
Newer Kindles have moved to KFX and EPUB delivery, but a Kindle Keyboard, an older Paperwhite or a legacy reading app will still open MOBI happily.
Does the cover come across?
Yes, the EPUB cover image is embedded in the MOBI along with the title and author metadata.
What happens to elaborate formatting?
MOBI supports a smaller slice of CSS than EPUB, so complex layouts are simplified. Paragraphs, headings, italics, lists and images all survive.
