It takes a few minutes. Any tool that emails files to a Kindle needs the same Amazon setting.
The Send to Kindle email guide walks through the Amazon side with screenshots.

| File | Works | Good to know |
|---|---|---|
| CBZ | Yes | The usual comic archive: the page images in a ZIP. |
| ZIP | Yes | A ZIP of page images. To send a folder of pages, zip the folder first. |
| CBR | When it's a ZIP inside | A CBR that is a RAR archive has to be extracted and zipped again first. |
| EPUB | Image-based comic EPUBs | Pages are taken in file-name order. Text EPUBs, like novels, don't work. |
| Yes | Each page is rendered at high resolution, then sized for your Kindle. | |
| JPG, PNG, WebP | Yes | Each image becomes its own book, so zip a chapter's pages into one file. |
More on each format: CBZ and CBR, PDF, which format to pick. The free converter takes CBZ, ZIP and image files up to 200 MB without an account.
Every page goes through these steps on its own, for the Kindle you picked.
Copied over as it is
The art covers 68% of the screen.
Sent with MangaSendr
The art covers 88% of the screen.

The art and the speech bubbles get as much of the screen as the page shape allows. More on white margins.
Each page is built at the size listed for your model below. PDFs are rendered at high resolution first, so small lettering stays crisp.
Black-and-white Kindles get greyscale pages with the contrast turned up, so blacks come out deeper than in the file. It's on from the start, and you can turn it off in Settings. On a Colorsoft or Scribe Colorsoft, pages keep their color.
A page that is wider than it is tall is rotated to fill the screen. Turn your Kindle to read it.
Pages turn like printed manga. For a Western comic, choose left to right when you upload in the web app.
The first page becomes the cover, with the title printed at the bottom, and volumes are named so a series sorts in order.
You pick your model once, and every page is built at this size.

Fire Force 01 (1 of 3)
Amazon's Send to Kindle email takes up to 50 MB per message, and a full manga volume is often bigger. MangaSendr splits it into as many parts as it needs, each small enough for one email. Every part gets its own cover and a name like “Fire Force 01 (1 of 3)”, so the parts sit in order. Send to Kindle size limits.
Sent volumes appear under Documents in your Kindle library. That's where Amazon puts everything that arrives by Send to Kindle email, so they sit apart from the books you bought in the Kindle Store. Each one has its cover and a title that sorts, so a series lines up in order.
The desktop app is optional and free to install. It can watch a folder on your computer: about once an hour it checks for new CBZ, ZIP or EPUB files and sends them to your Kindle.
It can also copy volumes to a Kindle over USB. That needs Calibre or Kindle Previewer installed on the computer, and a Kindle that shows up as a drive when you plug it in.
It runs on Macs with Apple silicon (M1 or newer) and on Windows 10 or 11. Sending to your Kindle from the app uses your free delivery first, then the license or the monthly plan. Get the Mac and Windows app.
It works on files you already have. If you need some, here's where to get DRM-free manga and comics.
MangaSendr emails Kindles only. For another e-reader, choose Save as file in the web app and copy the EPUB or CBZ over. The EPUB's pages are one 6-inch Kindle size.
Books bought in the Kindle Store and other locked files don't work. Only DRM-free files do.
One long vertical strip stays one page. Chapters already cut into page-height images work. Webtoons on a Kindle.
Your first volume is free and you don't need a card. After that it's $29 once, or $4.99 a month. Delivery to your Kindle is included either way.
