Manga to AZW3, and what to send a Kindle today
AZW3 is the Kindle format that replaced MOBI. Amazon introduced it with KF8 in 2011, and it is what Amazon own Send to Kindle pipeline converts your uploads into now: MOBI was dropped from that pipeline in late 2022. So there is a real oddity worth naming here. The one Kindle specific format this converter emits today is MOBI, which is the format Amazon itself has retired, while the format Amazon actually uses is the one we cannot yet produce.
That is why AZW3 output is on our roadmap and why this page exists. We are not going to pretend it is live: there is no AZW3 in our output list and the engine behind this site does not offer it as a target either. The good news is that it matters less than it sounds, because EPUB now reaches a Kindle perfectly well, and that path works today.
AZW3 output is coming soon
Not live yet. EPUB through Send to Kindle gets you an AZW3 on the device today, and MOBI is live here for older Kindles.

Convert to EPUB and send that
Send to Kindle accepts EPUB and converts it on Amazon side, into AZW3 as it happens. Pick your Kindle model in the device list, output EPUB, and the pages arrive sized for that screen. This is the route we would recommend even once AZW3 output ships.
Or use MOBI for an older device
MOBI output is live here and is the right pick for a pre 2016 Kindle that never got EPUB support through Send to Kindle. Choose a Kindle profile and select MOBI as the output format.
Or sideload a CBZ reader file
If you read in a comic app rather than the Kindle reader, CBZ output gives you the cleaned page images in a plain archive. It will not go through Send to Kindle, but it copies over USB.
Vote for AZW3 if you need it specifically
There is a roadmap card for AZW3 output. If you have a reason EPUB and MOBI do not cover, voting for it is what moves it up the queue, and traffic to this page counts alongside the votes.
The honest position on this one
AZW3 output is advertised as planned rather than quietly omitted, because a Kindle owner searching for it deserves to know where it stands and what to do instead. There is a vote button for it and no upload bar on this page, which is the right way round while the pipeline cannot emit the format.
EPUB is not the second best route
It is worth saying plainly: sending EPUB through Send to Kindle produces an AZW3 on your device via Amazon own converter. For most readers that is the whole job done, today, with the conversion that is already live here.
Frequently asked questions
Can I convert manga to AZW3 here right now?
No. Our outputs are EPUB, MOBI, CBZ and PDF. AZW3 has a roadmap card you can vote for, and this page explains the format meanwhile. We would rather tell you that than take your upload and hand back something else.
What is the difference between AZW3 and MOBI?
MOBI is the older Mobipocket based Kindle format, with limited layout control. AZW3 is KF8, which supports far more of the CSS and typesetting an EPUB can express, which matters for fixed layout and panel sized comic pages. Amazon moved to AZW3 as the Send to Kindle target and stopped producing MOBI there in late 2022.
If I cannot get AZW3 here, what should I actually do?
Convert to EPUB and use Send to Kindle. Amazon converts the EPUB into AZW3 for you, so the file on your device ends up in the modern format regardless. You lose nothing by going through EPUB.
Is AZW3 just a MOBI with a new name?
No, though the two often shipped inside one hybrid file during the transition years, which is where the confusion comes from. They are different formats with different capabilities, and a KF8 AZW3 can hold layout a MOBI cannot represent.
Why is AZW3 output real work rather than a setting?
Because the open source engine this site runs on does not offer AZW3 as an output at all. Its format list is Auto, MOBI, EPUB, CBZ, KFX, MOBI plus EPUB, and PDF. AZW3 exists inside it only as an internal detail of how MOBI files get built. Producing a standalone AZW3 means a new emit stage, so a promise about it has to be a real plan rather than a checkbox.
Can I read AZW3 files I already own by converting them here?
Not yet, and that is the other direction of the same gap. AZW3 input is also on the roadmap as its own card. The engine accepts CBZ, CBR, CB7, ZIP, RAR, 7Z, EPUB and PDF today, and reading an AZW3 means unpacking a Kindle container before the image pipeline starts.
MangaConverter runs on Kindle Comic Converter (KCC), the open source engine. KCC output formats are EPUB, MOBI, CBZ and PDF; AZW3 is not among them, appearing internally only as part of how MOBI files are built. AZW3 output is a planned addition here, and this page will host it once it works.
