Ebook Converter
Not every ebook is a wall of text. Comics, manga, scanned books and page PDFs are really stacks of images, and a generic converter treats them like prose: it reflows nothing, shrinks everything, and hands your e-reader pages it renders slowly and badly. Those books need each page rebuilt as an image sized for the exact screen that will show it.
MangaConverter does that rebuild: drop in an EPUB, PDF or comic archive and get an EPUB, KEPUB or MOBI with every page resized and contrast-tuned for your device, previewed live before you commit. If your book is pure text with no fixed pages, be honest with yourself and use Calibre or Send to Kindle directly; this tool earns its keep the moment images carry the book.

How it works
Upload your ebook or archive
EPUB, PDF, CBZ, CBR, CB7, ZIP, RAR and 7Z all work. Up to 20 files at once, 1GB each and 1000 pages per file, unpacked right in the browser.
Pick the e-reader it is for
Choose your exact Kindle, Kobo or reMarkable model. Pages are rebuilt for that screen, so a basic Kindle gets 1072 x 1448 pages instead of a one-size guess.
Check the live preview
Converted pages show up before you commit. If text looks soft or margins waste space, adjust the settings and re-preview in seconds.
Download and load it up
Grab the finished EPUB, KEPUB or MOBI and copy it to your device. Outputs stay available for 24 hours, then auto-delete.
Image ebooks are not text ebooks
A reflowable EPUB adapts to any screen because it is text. An image ebook cannot reflow: each page is a picture with a fixed shape, so the only way it looks right is to resize it for one specific display. That is the entire job this converter does.
When to skip this tool
If your EPUB is a plain novel, send it straight to your device: Send to Kindle takes EPUB directly (mind its roughly 50MB email cap) and Kobo reads EPUB natively. Come back the day you hit a scanned book, a comic or a PDF that reads badly.
Frequently asked questions
Which ebooks actually need this converter?
Image-heavy ones: comics, manga, artbooks, scanned paper books and PDFs of fixed pages. A text-only novel is already reflowable, and Calibre or Send to Kindle handles it fine without any page rebuilding.
What output format should I pick?
EPUB for Kindle (Send to Kindle accepts EPUB; Amazon dropped MOBI from it in 2022), KEPUB for Kobo so reading stats and the faster comic renderer kick in, and MOBI only for old Kindles that predate EPUB support.
Can it convert a PDF ebook?
Yes. PDF pages are extracted as images and rebuilt for your screen, which fixes the classic PDF-on-e-reader problems of huge margins and tiny type.
Is my library safe on a web converter?
Files unpack in your browser, conversion runs server-side, and every output auto-deletes after 24 hours. The engine is open source (kcc-cloud on GitHub), so you can also self-host the whole thing.
Conversion runs on Kindle Comic Converter (KCC), the open-source engine the comic and manga community has trusted for years, hosted here with a live preview so there is nothing to install.
