Split a volume at the Send to Kindle size limit
Send to Kindle takes 50 MB per email and 200 MB per web upload, and a long manga volume at scan resolution can beat both even after conversion. The planned size cap splitter lets you set that limit once; when a converted file would exceed it, the volume comes out as part 1, part 2 and so on, each under the cap, each with the page numbers that belong to it. We are being straight with you: it is not live yet, so this page does not offer it.
What works today is the target size option: it re-encodes pages until the whole file fits a size you name, which trades some image quality for the cap. The planned splitter keeps the quality and splits the pages instead, and the two can be combined when a volume is both long and heavy.
The size cap splitter is coming soon
This feature is planned, not live yet. Set a target size or use the Reader Shelf in the meantime.
Vote for this on the roadmapWhat the size cap splitter will do
Name the cap
A maximum in megabytes, with 50 MB and 200 MB offered as presets for the two Send to Kindle routes. The cap lives with the device profile so you set it once.
Split at a chapter when it can
When the file would exceed the cap, the volume is cut into parts. A cut lands on a chapter bookmark where one exists, and on a page boundary otherwise, never inside a spread.
Numbered parts, same metadata
Each part carries the title, series and volume number plus a part index, so the Kindle library sorts them in order and the cover appears on every part.
Until then: target size or the shelf
Set a target size to shrink the file under the cap, or skip Amazon entirely and pick the full file up from the Reader Shelf, which has no size limit of its own.
Honesty first
A splitter that cut through a double page spread or dropped the last page of a part would be worse than none. It ships when the cut points are right.
The live converter helps now
Target size brings most volumes under 50 MB today, because pages are rebuilt at the panel pixel size instead of print size, and the Reader Shelf has no cap at all.
Frequently asked questions
Can I split a volume at a size cap right now?
Not yet, and we will not pretend otherwise. The target size option shrinks a file to a named size today, and the Reader Shelf delivers any size without email.
Why split instead of compress?
Compressing past a point makes screentone muddy and linework soft. Splitting keeps every page at full quality and only changes how many files you send.
Will the parts read as one book on the Kindle?
They will sit next to each other as part 1, part 2 and so on under the same series name. The Kindle does not merge files, so the parts stay separate entries in order.
Will you announce when it is ready?
Yes. When the splitter ships it appears in the output options and this page hosts it. You can vote for it on the roadmap in the meantime.
MangaConverter runs on Kindle Comic Converter (KCC), the open-source engine, for the conversions that are live today. The size cap splitter is a planned output step after that engine, and this page will host it once it works.
