Manga built for a Boox screen
A Boox is the odd one out among e-readers, and it changes what a converter needs to do for you. Every current Boox runs full Android with the Play Store, so format support is not your problem: the stock reader already opens CBR, CBZ, EPUB, AZW3, MOBI, PDF and DJVU, and if you dislike it you install Mihon or KOReader or Perfect Viewer instead. What a Boox cannot do is invent pixels. A 824 by 1648 Palma and a 3200 by 2400 Note Max are the same library at wildly different page sizes, and a file built for the wrong one is either soft or cropped. That sizing is the part worth getting right, and it is what the planned Boox profiles are for.
We are being straight with you: there is no Boox entry in the device list yet. The conversion engine behind this site ships profiles for Kindle, Kobo and reMarkable only, so a Boox profile is a real addition rather than a label we can switch on. What works today is the Custom conversion profile with your panel size typed in, and the sizes are published below so you can do that in under a minute.
Named Boox profiles are coming soon
Not live yet. Use Custom conversion with your panel size from the table above, and the pages come out at exactly the right dimensions.

Find your panel size
Palma, Palma 2 Pro and Palma 3: 824 by 1648. Go Color 7 Gen II and the 7 inch Page and Leaf2: 1680 by 1264. Go 10.3 Gen II, Note Air6 C and the Note Air and Tab Ultra 10.3 inch line: 2480 by 1860. Note Max and Tab X C: 3200 by 2400. Note Mini C: 2048 by 1536. Picco: 480 by 800.
Choose Custom conversion and type it in
Pick Custom conversion in the device list and enter the width and height in pixels. The engine then builds pages at exactly your panel size, the same arithmetic a named profile would run. Every other control stays available: greyscale, margin cropping, spread splitting, right to left page turns.
Output CBZ or EPUB
CBZ is usually the better pick on a Boox, because you are reading in a comic app that wants page images and nothing else. EPUB works too and suits the stock reader. Skip KEPUB and MOBI: those are Kobo and Kindle firmware formats and buy you nothing here.
Copy it across
USB to the device storage is the plain route. Because it is Android, the alternatives are real: the built in browser can download the finished file from the Reader Shelf with a six digit code on a signed in account, or you sync it through a cloud app you install yourself.
Where these numbers come from
Every resolution above is read off Onyx official product pages, with the Kaleido colour grids taken from archived manufacturer spec tables where the current store page omits them. A profile is a promise about pixel sizes, so a model gets listed after its panel is checked and not before. The Nova Air C is missing from the table on purpose: its colour resolution is not published anywhere we could verify, and a guessed number would convert wrongly.
The current line, not last year
Boox turns its catalogue over quickly. The sizes above cover the models on sale now (Palma 3, Palma 2 Pro, Go Color 7 Gen II, Go 10.3 Gen II, Note Air6 C, Note Mini C, Note Max, Tab X C) and the recent models that share their panels, so a Note Air4 C or a Tab Ultra C owner reads the same 2480 by 1860 row.
Frequently asked questions
Can I pick a Boox model in the device list right now?
No, and we will not pretend otherwise. The engine behind this site carries Kindle, Kobo and reMarkable profiles only. Use Custom conversion with the panel size from the table above, which produces the same file a named Boox profile would.
Does a Boox even need converting? It opens CBZ already.
It opens the file, which is not the same as the file fitting. Boox lists CBR, CBZ, EPUB, AZW3, MOBI, PDF and DJVU as natively supported, so compatibility is genuinely a non issue. Converting is about page size, weight and contrast: a 100 MB scan resized to your exact panel turns pages faster, takes less storage and looks sharper than the reader app downscaling every page on the fly.
Which resolution do I use for a colour Boox?
The mono grid, always. A Kaleido 3 panel such as the Go Color 7 Gen II or Note Air6 C renders text and line art at the full 300 PPI mono resolution and colour at half that on each axis. Convert at the mono numbers (1680 by 1264, or 2480 by 1860 on the 10.3 inch models) and the colour layer takes care of itself.
Is the Boox Palma really a manga device at 6 inches?
It is a phone sized reader at 824 by 1648, which is a tall narrow page. Single pages read well. Double page spreads do not, so turn on spread splitting and read the halves in order rather than fitting a whole spread onto that width.
Why is my Picco different from every other Boox?
Because it is. The Picco is 3.97 inches at 480 by 800, and its published format list carries no CBR, no CBZ and not even PDF: text formats only, transferred through the BOOX Tiles app. It is the one Boox a comic archive will not open on.
Will you announce when the Boox profiles ship?
Yes. When they land they appear in the device picker and this page hosts them. You can vote for them on the roadmap meanwhile, which is how we decide what gets built next.
MangaConverter runs on Kindle Comic Converter (KCC), the open source engine, for the conversions that are live today. Its profile table ships Kindle, Kobo and reMarkable; named Boox profiles are a planned addition to the device table in front of that engine, and this page will host them once they work.
