Tools for getting manga onto a Kindle, compared
Send to Kindle on its own works when your manga is already an EPUB under 200 MB. KCC and Calibre are free desktop converters: KCC leaves the sending to you, and Calibre can email books but doesn't split big ones. MangaSendr converts, sizes, splits and sends from any browser, and your first volume is free.
We make MangaSendr, so keep that in mind as you read. Facts about the other tools come from their own documentation and Amazon's help pages, linked at the bottom of this page.
The four routes side by side
Every route ends with Amazon's Send to Kindle or a USB cable. The difference is who does the steps in between: opening the archive, sizing the pages, keeping each file under Amazon's limits, and sending it.

Each route, step by step
Send to Kindle alone
- Start with an EPUB or PDF you own.
- Upload it on the Send to Kindle website (up to 200 MB), or email it to your Kindle's address from an approved address (up to 50 MB).
- It appears in your Kindle library.
KCC, then Send to Kindle
- Install KCC, plus 7-Zip and Kindle Previewer if your files and output format need them.
- Pick your Kindle's profile and turn on manga mode for right-to-left books.
- Add the file and convert it.
- Copy the MOBI file to the Kindle over USB, or upload the EPUB on the Send to Kindle website.
Calibre
- Add the CBZ to your Calibre library.
- Open Convert books, pick EPUB or AZW3 and a Kindle output profile or a custom size, and set the comic options.
- Convert it.
- Email it to your Kindle if it's under 50 MB, or connect the Kindle by USB and send it as AZW3.
MangaSendr
- Create an account, add your Kindle's Send to Kindle address and approve delivery@mangasendr.com in your Amazon settings once. A free 5-page test checks the setup.
- Send one file, or up to 50, from any browser.
- Each one is converted for your Kindle model, split if needed and sent. It usually shows up within a few minutes.
The free routes work well, and if you only put a volume on your Kindle now and then, they may be all you need. MangaSendr is for when you send often enough that the steps in between start to add up. Pricing shows what's free and what the license covers.
Questions
What's the free way to get manga onto a Kindle?
Convert the file to EPUB with KCC, Calibre or MangaSendr's free converter, then upload it on Amazon's Send to Kindle website, which takes files up to 200 MB. All of that costs nothing.
Which tool is best for a Kobo?
KCC. It has Kobo profiles and makes KEPUB files. Calibre also converts for Kobo. MangaSendr emails Kindles only, and its downloads are sized for a 6-inch Kindle.
Where do the manga files come from?
From you. None of these tools provides manga. They work on DRM-free files you already have, such as volumes from Humble and Fanatical bundles or DRM-free stores. Where to buy DRM-free manga lists legal sources.
What does MangaSendr cost?
Your first volume is free and you don't need a card. After your free volume, the license covers multi-file sending, splitting, automation and sending from any device, with delivery included. It's $29, paid once, with a 14-day money-back guarantee, or $4.99 a month. Pricing has the details.

Send one volume and compare for yourself
You don't need a card, and there's nothing to install. After your free volume it's $29 once, not per volume, and it doesn't renew.
