Put any EPUB on your Kindle in two minutes. We convert it to the right format and send it to your device — no cables, no software.
EPUB is the standard ebook format used by almost every store and reader in the world, except Amazon. Kindle devices only open Amazon's own formats, so an EPUB copied to a Kindle simply does not show up in the library, and one attached to an email may bounce or arrive unreadable.
The fix is to convert the EPUB into a Kindle format first. That used to mean installing desktop software and fiddling with cables. EPUBKit does the conversion in your browser and delivers the book to your Kindle over Wi-Fi, so the whole thing takes about two minutes.
Every Kindle has its own email address ending in @kindle.com. When you enter it and click Send, we email the converted book to that address from kindle@epubkit.com. Amazon receives it, checks that our address is on your approved list, and pushes the book to your device the next time it connects to Wi-Fi. It appears in your library like any other book, with your reading position synced across the Kindle app too.
We keep nothing: the file is deleted from our server within an hour, and your Kindle address is used only for that one delivery.
Any EPUB without DRM: books from Project Gutenberg and Standard Ebooks, titles bought from DRM-free stores, files from independent authors, documents you created yourself, and books you own that came as EPUB. Books purchased from other stores with DRM protection cannot be converted; that restriction is set by the seller, not by the format.
If your file is a PDF rather than an EPUB, convert it to EPUB first with our PDF to EPUB tool and then send it here. The result reads far better on a Kindle than the original PDF.
Kindle devices use Amazon's own formats, AZW3 and MOBI, and do not open EPUB directly. Converting the EPUB to one of those formats solves it. EPUBKit does the conversion and can send the result to your Kindle in one click.
In your Amazon account go to Manage Your Content and Devices, then Devices, and select your Kindle. Its email address ends in @kindle.com. You can also find it on the Kindle itself under Settings → Your Account.
Usually between one and five minutes if the Kindle is connected to Wi-Fi. If it is offline, the book arrives the next time it connects.
You do not need to choose. EPUBKit converts to AZW3, which works on every Kindle made since 2011 and gives the best formatting. Only tick the old-Kindle option if you own one of the very first models (Kindle 1, 2, DX or Keyboard), which need MOBI.
Three things: that kindle@epubkit.com is on your approved sender list in Amazon, that you typed your Kindle address correctly (it ends in @kindle.com, not your personal email), and that the Kindle is connected to Wi-Fi. Amazon also sends a notice to your personal email if a document is rejected.
Yes. Conversion and Send to Kindle are both free, with no signup and no watermark. Files are deleted from our server after one hour.
